K&N XStream Air Filters Add Airflow for Motocross Motorcycles and Sport ATVs

XStream motocross air filter product view

The XStream line of motocross air filters add intake surface area for amazing airflow

K&N’s XStream filter systems blow the lid off conventional filter technology. Read on to see that that claim is not hyperbole. Both the XStream motocross filter and the XStream Powerlid for sport ATVs take airflow to another level by adding more surface area to your intake.

XStream Motocross Filters

There are times when a customer’s unsolicited review of one of our products speaks volumes. After purchasing, installing, and testing the XStream YA-2506XD filter in his motocrosser, Blake G. of Murrieta, California, told us what he thought.

“I give this product 10 stars out of 5,” Blake said. “The air filters are absolutely amazing. Hands down the best air filter I have ever (used). Such a crisp, accurate power on the bottom end and a stretch of strength on the top end. Never have I once in my life changed a single thing on my bike and got such a great outcome.

XStream filters offer up power, performance, and easy installation

"I will continue to run K&N oil and air filters in my bike for as long as I can ride. It's so easy to feel the difference in my friend's standard foam air filters. There is just no comparison. And another big perk is the easy installation, I love everything about the filters and I'm blown away that riders still tolerate old fashioned foam filters. It is the best investment you could make.”

So what is so revolutionary about the XStream series of air filters? Let’s take a look. K&N has developed a filter system that replaces what would normally be a solid filter top with an additional open filter surface area. This additional filter cap provides a large surface area that adds significant airflow to the engine.

That added airflow results in the potential for more berm-blasting power, more hole-shot acceleration, and enhanced overall performance. That power does not come at the expense of engine protection. That same large filtration area adds up to a substantial dirt holding capacity. K&N’s oiled, cotton gauze filter media has been proven on racetracks for over 4 decades.

K&N makes XStream series motocross filters for virtually every popular motocross bike. If you ride a Yamaha YZ, the YA-2506XD is your likely performance solution. The part for your Yamaha WR is YA-4503. The YA-2506XD filter works on a number of Suzuki RM applications along with the SU-2596, and the KA-2504. Your Kawasaki KX will love the KA-2506XD, KA-2504, and KA-1297. Honda riders are not left out as the HA-4503XD, HA-4509XD, HA-4513XD, HA-2505XD, HA-1507, and HA-4502 have your CRF covered. The KT-4511XD and KT-5201 are the Xstream filters for many KTMs. Most Husqvarna models use the HU-1200 filter.

All of the XStream filters are fully washable and reusable, making them ultra convenient in paddock or on the trail. Filter recharge kits like K&N’s convenient 99-5050 or 99-5000 make the job simple.

XStream Powerlid for Sport ATVs

The Powerlid shares the design concept of the other Xstream filters. The sport ATV Powerlid replaces the restrictive air box lid and snorkel with a K&N high-flow air filter cap. This additional surface area provides increased air-flow and protection in extreme conditions.

The added bonus is that each Powerlid includes a fitted K&N DryCharger for increased protection in severe conditions. K&N will also supply all necessary jets to properly tune your ATV for the increased airflow.

XStream Powerlids come with a DryCharger and jet kit

The K&N SU-4002-T fits some Arctic Cat DVX400, Arctic Cat DVX400 TS, Kawasaki KFX400, Suzuki LTZ400 QuadSport Z, and Suzuki LTZ400 QuadSport Z LE models. The K&N HA-4504-T, HA-4506-T, and HA-4099-T, cover most models in the Honda TRX 400 and 450 series. The Powerlid for the Yamaha YFZ350 Banshee is the YA-3502-T, the YA-4504-T for the YFZ450/SE, and the YA-6601-T for the YFM660R Raptor.

Note that when using a Powerlid, an internal air filter is still required. Of course K&N has the perfect filter for that purpose as well. A K&N filter teamed with a Powerlid ensures the ultimate in potentially power boosting airflow.

All of the game-changing XStream filters come with K&N’s One-Year Limited Warranty. Check the K&N website to see if your motocross bike or sport ATV is on the extensive application list. If so, K&N has an XStream filter or Powerlid for your ride. You can also use K&N's online application search tool for all of your other oil and air filter needs.

K&N Clamp-on Air Filters Add Performance to a Range of Powersports Applications

K&N universal pod filters on a Harley-Davidson flat track race motorcycle

K&N universal pod filters are a staple in the professional flat track paddock

Modified, performance, and competition motorcycles and ATVs require high airflow and effective filtration. Whether you ride a modified minibike, a mid-displacement motocrosser, or a full-on flat track racer, K&N clamp-on pod filters have you covered. In fact, anything that has an engine is a likely candidate for a K&N clamp-on filter. All of the K&N pod filters are designed to increase power and throttle response.

The filters are formed around K&N’s legendary cotton gauze filter media that is fully washable and can be re-oiled for years of dependable service. All of these filters come with K&N's one-year limited warranty.

Specialty Air Filters for Modified Motorcycles, ATVs, and More

Small and mid-displacement engines can benefit greatly from a free-breathing intake. K&N’s specialty air filters are the logical starting point for adding the performance that results from added airflow.

A K&N pod filter and surface sealer

K&N pod filters come ready to clamp on to your modified intake application

Engine and intake modifications are as wide-ranging as the owners that create them. K&N makes a full range of pod filters that fit most any application. Carburetor and intake sizes from 16mm to 28mm can be accommodated from the incrementally sized RC-2540, RC-0790, RU-0060, RC-2310, RC-1070, R-1080, and R-1100 filters.

In addition to the intake size options, the filters are also available in a range of angles and offsets for various applications. Conical, oval, and round shapes are available. These sizing, shape, and placement options make these filters extremely versatile. They can even be fitted to racing vehicles, radio-controlled cars, generators, snowmobiles, tractors, and many other applications.

To add another stage of filtration and extend the service intervals, K&N offers a range of pre-chargers for the filters. The RC-2540PK, RC-0790PK, 22-8008PK, 22-8028PK, 22-8029PK, or 22-8048PK can be added to the intake depending on the application.

K&N pre-chargers on a flat track racer

Racers know the benefits of K&N pre-chargers, like these at the AFT Arizona Mile

K&N also has a range of pancake filters that fit mid-sized motorcycles like the Kawasaki KLX110 and other applications with limited clearance. Various carburetor intake sizes can be fitted with filters like the RC-0170, RC-2870, and RC-0330. The RC-0170DK pre-charger can be added to several of the applications.

It should be noted that some of the filter applications could require re-jetting.

Larger Displacement and Competition Air Filters

It doesn’t take long when walking the paddock of any professional flat track race to identify the racers' filter of choice. K&N has a four-decade legacy in providing power and protection on the dirt oval. That same filter technology is perfect for a wide variety of powersports applications.

K&N gives detailed specifications and dimensions for a perfect fit for your application

The K&N large-body filters are designed with abundant filter media to allow extra dirt holding capacity without restricting air flow. More filter surface area significantly increases airflow which adds the power and torque needed when powering out of a turn or accelerating in the straights.

The performance and protection benefits of the larger K&N pod filters are not limited to competition. Again, these filters are built in a wide variety of lengths and body shapes to fit a full spectrum of applications.

The oval model RU-1230, RU-1240, and RU-1260 filters come in lengths of 6”, 7”, and 9” respectively. These pods have a 10° angle on the 1” intake flange length. The 7" RU-1830 and the 9" RU-1840 "D" Oval models also have a 10° angle but employ a 2 1/8" intake flange length.

While these filters are a direct fit for many Mikuni carburetors, they are universal, and other applications will benefit from the added protection and airflow of the pods. K&N makes pre-chargers that can be added to all of these filter models. The RU-1230PK, RU-1240PK, and RU-1260PK have you covered – literally.

Again, these free-flowing universal pod air filters may require jetting changes in certain applications.

K&N pod filters are equally at home on vintage and modern motorcycles and ATVs. Whether you ride a modified minibike, middle-displacement motorcycle, ATV, or even an open-class flat tracker, K&N likely has the perfect filter for your bike. Don't forget to check your garage for other engines that will benefit from K&N clamp-on filters.

Martino Motorsports Approaching 50th Year On Drag Racing Circuit

The Martino family including Tom, Neil, Jimmy and Ryan stand with their dragster.

The Martino family stands behind its dragster at one of the many tracks they race

Reaching a 50th anniversary is a major achievement whether it is for a birthday, wedding, or the establishment of a business. It is also a big deal for a racing team. In 2020, Martino Motorsports will celebrate its 50th year on the drag racing circuit.

Founded by Youngstown, Ohio resident Tom Martino and his brothers Neil and Jimmy, Martino Motorsports was created in 1970.

“Tom always had a passion for cars. When he reached the legal age to drive, he took his daily driver to a racetrack. He had success and it went on from there,” explained Ryan Martino, Tom’s son, who is now the secondary driver for the team and who has been contributing to it since he was 12 or 13 years old.

The Early Years

During those early years Tom, Neil, and Jimmy Martino successfully took on local drag racers and then continued on to the national level. They continue to race in National Hot Rod Association (NHRA) and Professional Drag Racers Association (PDRA) events.

“They did quite well racing a Dodge Dart in the Super Stock Classification,” added Ryan.

He noted that his dad has been well decorated in his drag racing career.

“He has quite a win record, but it's difficult to keep track of wins going back more than 45 years,” he said.

Ryan’s Participation

Ryan was born in 1981.

“You can say that I was born at a racetrack,” quipped Ryan. “I grew up at the track. As I got older I started to contribute to the team. It was an easy transition helping my dad and uncles become a force in drag racing.”

Ryan’s inaugural years with the team was assisting in the basic maintenance of the car. He did not get a formal education on automobiles. Instead, his father handed down the knowledge of automobiles and drag racing to him.

“It was all hands on,” he explained. “I also learned about racecars and racing from being around great engineers and staffs at engine shops who took the time to teach me. I took what I learned and applied it to our race team.”

He didn’t start driving for the team until he was 22 or 23 years old.

“I attended and played football at Youngstown State University. So, due to NCAA rules, I couldn’t race for the team until I finished with my collegiate football career,” he said. “So soon after my last football game, I climbed behind the wheel of a super comp dragster.”

The Martino dragster launches for the finish line.

Martino Motorsports' dragster blasts off the starting line

Ryan noted that about five years later he advanced his race license so that he could compete in the top dragster category for Martino Motorsports. It was easy for Ryan to transition into driving as well.

“When I ran my series of first quarter-mile passes, everyone at the track gladly signed off on my license to permit me to race dragsters,” he explained. “From that point on, I gained my NHRA competition license and got right into the circuit.

“What’s so unique about drag racing is that you can walk right in and race at the top level if you have the right resources available – a car and the financial resources to compete,” he said.

Ryan volunteered that Martino Motorsports is unique because all the members of the team have full time 9 to 5 jobs.

“My dad and I work more than 40 hours a week on regular jobs to maintain our race program to compete on weekends,” he said. “Many racers are on teams with multi-million dollar budgets and they are associated with companies that provide resources to compete at this level. We are a father and son team and we put in the hours to put our cars on the track.”

Ryan pointed out that everyone who works for the team also has 9 to 5 jobs and that affects who can attend races.

“Sometimes it’s just me and my dad who travel,” he said. “On some occasions, my uncles and grandfather will travel with us. There are also times when friends travel with us. For example, when we race near Chicago friends from that city will come out and help us out.

Budgeting time to perform what must be done when running a racing team can be challenging. Ryan noted that he and his dad have been able to do it because Tom works at night and Ryan works during the day.

“So whatever my dad can’t get to during his time on the car, I do,” Ryan said. “On Friday evenings, Saturdays and Sundays we both work on the car.”

The Team

Ryan noted that the NHRA has divided the country into seven divisions. Martino Motorsports races in the North Central Division, which includes stops at St. Louis, Missouri; Bowling Green, Kentucky; Columbus and Norwalk, Ohio; Joliet, Illinois; and Indianapolis, Indiana.

The fact that both Tom and Ryan have 9 to 5 jobs also influence what races they can compete in.

“We dedicate a majority of our race schedule to the NHRA because they offer more than eight races that you need to claim a championship. So we often look for races that are scheduled on weekends. We will also run in a couple of Northeastern Division races because they are scheduled during weekends that are convenient for us.

“We also compete in ADRL and PDRA events, but their races are a little different. They run 8th of a mile instead of a quarter mile. They also have a little bit different format. They race Fridays and Saturdays and we travel back home on Sundays. That’s appealing to us. However, you have to be at those races on Thursdays and be ready to go on Friday to do the two-day event,” explained Ryan.

Martino Motorsports spends a lot of time preparing for a race.

“First and foremost we have to go through the entire car and make sure everything is sound starting the day after we come home from a race. If new parts are needed we order them so they are delivered in the early part of the week. We perform basic maintenance to make sure our car is race ready when we leave the house without a doubt,”

Finally, they are crazy about keeping the car clean.

“We make sure that the car is very clean,” Ryan said. “That’s because it is often used in ads and is photographed and videoed at the track. In addition, one of our associates is Meguiar’s Wax. Keeping the car show clean even when we race is imperative to us.”

To show that this is a major part of their preparation, Ryan noted that between races many racers comment that their car looks so clean that it looks like it’s never raced.

Ryan noted that he and his father often research a track before a race.

“For example, we know guys who run the same tracks we do. They give us tips about the condition of the tracks. Some tracks have bumps here and there that will throw our car left and right. Sometimes you have to tune the car a little different to compensate. This helps us determine what kind of tune-up we will try.”

He also noted that they put cameras on the car focused on major components so that they can ascertain how well those components are performing during a run.

“The cameras are focused on certain parts of the car including the rear-end suspension to see how it is handling. We focus on different parts of the engine to make certain that everything is working okay. However, we are most concerned about the suspension because we want to know if there is enough downforce on the tires and that there is a nice tire print on the track. We are always studying the front and backend of the car to see if the wheels are picking up too high and if we should tame that down a little bit. We are also looking for tire shake. We can slow down the video to see if the tires are hazed and if they are sticking too well to the track. We look at the videos between races on a TV in our trailer. We study them and make adjustments for the next pass.

“Those videos also make pretty cool highlight clips that we show on our Facebook page and on YouTube. We also give them to sponsors so that they can post them on social media to show how their components work on a racetrack. Mickey Thompson Tires, K&N filters, and Strange Engineering, have used our videos."

The Sponsors

Ryan pointed out that he and his dad handle all aspects of marketing their race program.

“We work hands-on with our marketing partners,” he said. “We encourage them to become involved with the team’s racing program. We always pound the streets to get new partners, although it is hard to do because of our fulltime jobs. Even with the constraint, we make sure that our sponsors get exposure on a daily basis and we do a lot of community service projects for sponsors.

K&N is a major marketing partner of Martino Motorsports.

“We started with K&N in the early 2000s. It’s been a great partnership ever since. It’s an honor to represent K&N and all that they do for racing. It’s very cool to see the K&N brand recognition when you go out on the road and see people proudly display the K&N logo on the back windows of their cars. They recognize it as a great company even if they aren’t race fans.

“K&N makes a great product,” continued Ryan. “We use it on every application including our race and family cars, our generators, golf cart, and motorhome. We highly recommend their products to everyone.”

The Martino family uses K&N air and oil filters on their racecars and daily drivers as well as a hood scoop, which Ryan claims is an essential part of the racecar. They also use K&N cold air intakes on their daily drivers. Moreover, they use K&N filter cleaning kits to cleanse all the K&N filters.

Ryan also volunteered that Martino Motorsports often try out new products for their sponsors when there is downtime.

“We often help them with R&D and assist in marketing blasts on social media and testimonials,” he said.

In 2017, the team has competed in 10 events to date. According to Ryan, there is only one more race to claim for NHRA competition to try to win a championship.

“Racing is a very numbing sport,” said Ryan. “You can be on the top of the mountain one week and the next event a fraction of a second can send you home early.”

Replacement Cabin Air Filter for 2013-2017 Lexus Coupes and Sedans

The tough urethane frame assures a tight seal for K&N Cabin Filter Filter

A K&N replacement cabin air filter helps protect you from most pollen, mold, dust, and bacteria

Lexus has long been admired for consistently delivering the quietest cabin for each of the vehicle segments in which it competes. Lexus pursues every opportunity to reduce the amount of noise, no matter the source, that reaches passengers. This dedication goes well beyond soundproofing. Aerodynamics are obsessively tested, and even the wheels are designed to reduce the sound they generate as they roll down the road.

Owners who purchase a Lexus appreciate the efforts made to isolate driver and passengers from the outside environment. And there is one area where an owner can help maintain and even improve the protection of their passengers – with a K&N VF2057 cabin air filter. The K&N VF2057 fits some Lexus GS350, Lexus GS450h, Lexus IS200t, Lexus IS250, Lexus IS300, Lexus IS350, Lexus RC F, Lexus RC200t, Lexus RC300, and Lexus RC350 models.

For many years Lexus has installed cabin air filters in their vehicles to protect occupants from the dirt, dust, pollen, and spores that are drawn into the fresh air vents. And while those particles are a nuisance on the outside of your vehicle, they can potentially be a health hazard when they enter the interior. Should you or a passenger suffer from a temporary or permanent respiratory ailment, these spores and mold can make life miserable.

K&N Cabin Air Filters perform for up to 10 years or 1,000,000 miles

Everything you need to install a K&N replacement cabin air filter is in the box

In order to be effective, the filter needs to replaced on a regular basis. By not servicing your cabin air filter per the recommended interval results in a lack of fresh air entering the cabin and a heavier load placed on the heating and air conditioning system. And under some conditions, you may have to service the cabin air filter more frequently. These circumstances can include if you drive in a dusty area or through the desert, your filter may load more quickly, and if you live in a damp climate you might notice persistent bad odors that come from bacteria from mold growing on the cabin air filter.

A great solution is the washable and reusable K&N cabin air filter, which typically exceeds the lifespan of standard filters. There's actually an environmental impact. If everyone with a cabin air filter were to replace and discard their filter at the intervals recommended by the manufacturers, it would add hundreds of thousands of filters to landfills across the country.

In addition, K&N cabin air filters are electrostatically charged to grab and hold dust and other airborne particles. They also help control odors while they help capture and trap most mold, mildew, fungus, spores, bacteria, and germs. K&N cabin air filters are also manufactured to fit your vehicle perfectly and seal tightly, thanks to the precision-engineered polyurethane frame. In addition, each filter comes pre-treated and is ready to install straight out of the box.

Cleaning and renewing a K&N Cabin Air Filter takes just minutes plus drying time

K&N reusable cabin air filters can keep thousands of single-use filters out of landfills

Made of a unique non-woven synthetic material, K&N cabin air filters are an easy replacement upgrade for your vehicle's cabin air filter. Replacing the filter is a straightforward task - it is as simple as swapping the old, dirty filter for a new one. To make the process easier, detailed installation instruction sheets are included in the shipping carton with the filter.

The only maintenance required for a K&N cabin air filter is a service you can do yourself in no time at all. At intervals of about 12 months or 12,000 miles, use the K&N 99-6000 cabin air filter cleaning kit to easily renew and re-oil your cabin air filter, which brings it back to virtually new condition and ready to continue to protect your car’s cabin and its passengers. Your K&N cabin air filter is designed to last for years of use and is guaranteed by the K&N 10-Year/Million Mile Limited Warranty.

The K&N VF2057 is designed to fit the following vehicles:

K&N Products Well-Received At The Industry-Only China Auto Salon In Shanghai

The Nissan GT-R Nismo was selected to best represent the ambitions of car tuning in China

The modified Nissan GT-R Nismo in K&N colors was a big attraction in the K&N booth

In a very brief period of time, China has become the largest new vehicle market in the world. It first took the lead position in 2009 when it experienced a 46-percent growth over the previous year, and then another 32 percent growth in 2010. While annual increases have recently slowed to single digits, sales are still climbing.

Car shoppers in China can choose from imported cars, vehicles built under a joint venture agreement such as Ford, Toyota, Mazda, and GM, and indigenous manufacturers like Geely Automotive, FAW Group, and Dongfang Motor Company.

K&N Engineering has been an active participant in the growing aftermarket that trails these record-setting vehicle sales; the company has attended the China Auto Salon in Shanghai, the preeminent aftermarket event in the country as a member of the SEMA delegation. And like the SEMA Show, the China Auto salon is not open to the public – just exhibitors, buyers, and the motoring media.

K&N displayed a range of products from air and cabin filters to cold air intake kits

The sizeable K&N booth made an impression on show-goers as well as displayed the complete line

According to David Hill, Sales Manager for K&N, “This is our first year with our own dedicated booth, but we have previously attended as part of the SEMA delegation in 2016.”

Last year, K&N utilized the China Auto Salon as an opportunity to meet with some of the key distributors in the country. For 2017, K&N stepped-up its presence with the addition of a sizeable booth at the show. This allowed the company to meet with a larger number of buyers in various distribution channels.

Hill was pleased with the results from the show and K&N’s growth opportunities in the market. “We received a very positive reaction to K&N products. Car tuning in China is a relatively new phenomenon there, but they are very enthusiastic about it. K&N is established in the market, but we are looking to rapidly expand the brand's presence in the market, hence the reason for the booth.”

And what was displayed in the booth? “We presented all the products, but the focus was air filter elements and cabin filters,” the David explained.

K&N received great media coverage and word of mouth after their participation in the show

Over the course of the show the booth was visted by thousands of buyers and media

China has a mixed bag when it comes to the range of vehicles available – imported, joint venture, and Chinese-developed. How is K&N addressing this market? “We are currently offering a wide range of products for imported cars and locally-manufactured international brands, but also for some domestic Chinese brands as well,” Hill explained.

“K&N is currently working on a busy development schedule to increase our range for China, with at least 40 new filters currently being worked on, with 20-25 new parts numbers due for release this year,” he added.

“We were really excited to attend this year’s China Auto Salon and look forward to returning next year. The enthusiasm for K&N was really great to see and the show provided a great platform to promote our brand and have the opportunity to display our full range of products,” Hill concluded.
