American Superbike Champion Toni Elias shows off the K&N race filter for the Suzuki GSX-R1000

K&N Direct Replacement Sport Bike Filters

K&N has a nearly half-century legacy of producing the world’s finest washable, reusable filters that are direct replacements for restrictive stock air filters. While these filters allow a substantial increase in airflow, they require no engine management modifications for their performance benefit. They are also street legal in most states.

K&N direct replacement filters feature multiple layers of our legendary oiled, pleated, cotton gauze filter media for performance-enhancing airflow. The reduction in restriction that the filters provide is part of the K&N design goal of increased horsepower, torque, and throttle response.

K&N offers street and race-specific filters for many sport bikes like this one for Honda's CBR1000RR

K&N Race-Spec Sport Bike Filters

Track day, closed course, and racing bikes will benefit from the raw power that K&N’s race-spec air filters will provide. These filters are designed with two plies of filter media and fewer pleats than our standard K&N high flow air filters for the ultimate in airflow.

Unlike K&N’s direct replacement filters, our race-spec units will require remapping of the engine’s fuel management system. They work well with full-race exhaust systems and other high-performance modifications. Race-spec filters are not for street use.

These filters fit directly in the factory airbox and are fully washable and reusable for years of reliable service. Simply put, you will not find a better all-out performance filter for race and track applications – period.

K&N street duty filters give excellent filtration. The Aprilia AL-1010 filter test is shown here

Look below for the numerous sport bike manufacturers and models that are candidates for both the standard K&N high-flow filter and the race-spec, track-only model. For specific model years and applications, use the K&N search by vehicle tool to search K&N's comprehensive online portfolio of filters.

Aprilia:

Aprilia is the perfect starting point for our look at bikes that can be fitted with either a K&N direct replacement or a race-spec air filter. In the relatively brief history of the company, Aprilia has taken 54 world championship titles and has won an impressive 294 Grand Prix races.

The Italian company’s sporting flagship, the RSV4, and the exciting Tuono are prime candidates for either of K&N’s purpose-built air filters. The standard K&N AL-1010 will keep the Aprilia models street legal while giving a substantial boost in power-producing airflow. The race-spec AL-1010R will give a race or track day Aprilia the potential for even more horsepower and torque.

BMW:

The Bavarian beast of a sport bike, the BMW S1000RR, has become a staple on the podium of World Superbike racing as well as a favorite of sport-oriented street riders. As such, street riders and racers both have a great choice of air filter for the bike.

Honda:

The sport bike legacy of the venerable Honda marquee is legendary. From local club racing all the way up to MotoGP, Honda is a front-runner.

Honda’s middleweight speedster, the CBR600RR can be fitted with the HA-6007 for street use, or the HA-6007R for the track. Honda’s liter-sized 1000RR will benefit from the K&N HA-1008 for the street and the HA-1008R for the track.

Kawasaki:

Kawasaki and speed have become virtually synonymous over the decades. K&N makes both street and race-spec air filters for two bikes in the Kawasaki sport bike family. The ZX14R also has an application-specific K&N filter option.

ZX6R 600cc Ninja owners can choose the street model KA-6007 or the closed-course KA-6007R version. The applications for the 1000cc ZX10R Ninja are the KA-1011 for the street, and KA-1011R for the track. The big and bad ZX14R Ninja will use the street-biased KA-1406.

Suzuki:

Every K&N sport bike filter is carefully engineered for a perfect fit in the factory air box

The Suzuki GSX-R600 and GSX-R750 can be fitted with the K&N SU-7511 for street duty, and the SU-7511R for race and track applications. Owners of the fire-breathing GSX-R1000 can choose the street-specific SU-1009 or the race-spec SU-1009R. Suzuki GSX1300R Hayabusa riders can choose the SU-1308 street filter or the SU-1308R race filter.

Yamaha:

The Yamaha YZF line is race tested, but fully at home on public streets. Like the other sport bikes we have discussed, the Yamaha is a candidate for both street and track-only K&N filtration.

The 600cc YZF R6 will use the YA-6008 on the street and the YA-6008R on the track. YZF R1 street pilots will use the K&N YA-1009 or YA-1015 and racers of the 1000cc sport bike can opt for the YA-1009R or YA-1015R depending on the model year.

The K&N air intake systen for 2017 F250 & F350 Super Duty adds power and increases response

The 6.2L V8 was designed from the outset as a truck engine, so durability was key to the design. The engine features a deep-skirt cast iron block with cross-bolted main caps, two-valves per cylinder, SOHC aluminum heads with roller-rocker shafts, and two spark plugs per cylinder, as well as dual-equal variable cam timing. And while torque has been increased, horsepower is the same 385 HP as in previous years.

If you’re looking for a horsepower increase for your 2017 F250 or F350 Super Duty, look to K&N. The K&N 77-2588KTK air intake system adds 18.96 estimated horsepower at the wheels. That’s an instant increase in performance and throttle response.

Fresh air first enters a 7.5-inch tall RC-5179 K&N high-flow air filter positioned within a heat shield that installs into the space of the factory air box. The heat shield protects the cool incoming air from being affected by high underhood temperatures. The cooler the air is as it flows into the engine, the more power the engine can generate.

Much of the performance increase can be attributed to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media. This filter media offers a greater surface area and thus less resistance than traditional filters.

The K&N air intake replaces the stock air box and includes a heat shield to keep intake temp down

Further, the K&N air intake tube significantly reduces restriction to incoming airflow over the stock item, as well as calms power-robbing turbulence. Air passes through an aerodynamically-verified black powdercoated mandrel-formed aluminum intake tube directly into the engine’s throttle body. The intake tube accommodates the factory mass air sensor, fuel pressure hose, and crankcase vent hose.

Best of all, the K&N 77-2588KTK can be installed in 90 minutes or less with simple hand tools like a ratchet set, a few screwdrivers, and a couple of wrenches. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to your car that come included in the package.

The K&N conical air filter can go 100,000 miles between cleanings, depending on conditions

At intervals of 100,000 miles (depending on your driving conditions) use the K&N recharger kit 99-5000 to quickly clean and refresh your K&N air filter, preparing it for another 100,000 miles of driving.

The K&N air filter you purchase is designed to last the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement.

The K&N 77-2588KTK is designed to fit the following vehicles:

Harrison Burton wins his first NASCAR K&N Pro Series East championship at Dover

Burton won the National Fallen Firefighters 125 presented by Carl Deputy & Sons Builders and erased an eight-point deficit to capture his first K&N Pro Series East championship.

“What an honor to win both the race and championship at Dover, it’s pretty freaking cool,” Burton said. “It’s what I dreamed to do as a kid, win races at tracks like this and win NASCAR championships. To come out and do that is pretty surreal. I’m pretty pumped up about it.”

Burton was eight points behind Todd Gilliland in the K&N Pro Series East standings before the race at Dover. Gilliland ran into trouble when he blew a tire on lap 56. He dropped out of contention and cleared the way for Burton to take the championship. Burton still had to finish the race and collect enough points to pass Gilliland for the K&N Pro Series East title.

Harrison Burton is the youngest driver to win a NASCAR K&N Pro Series East championship

“This race kind of caps it all off for this team,” Burton said after the race. “A bunch of guys who never quit and I’m glad I fit into that system where people that put everything we got into what we’re doing. Now that it’s all come to fruition and we got to bring home two trophies, it’s a big relief and we’re going to go have fun now.”

Burton won his fifth race of the season. NASCAR Monster Energy Cup Series driver Joey Logano was the youngest driver to win a K&N Pro Series East championship at 17 years, 3 months, 28 days in 2007. Burton ended up with 593 points, eight points ahead of Gilliland in the final K&N Pro Series East standings. Burton joined his dad, Jeff Burton, as a NASCAR race winner at Dover International Speedway. Jeff Burton won the Cup Series race at Dover in 2006.

Harrison Burton won five NASCAR K&N Pro Series East races including the season finale at Dover

“This one is really disappointing,” said Gilliland who leads the NASCAR K&N Pro Series West championship standings with two races to go. “I felt like we had pretty good control of it going in here. We were just as fast as Burton in the race. Just having a tire go down like that is heartbreaking for sure. I’m really proud of everyone at Bill McAnally Racing. We’ve had the fastest cars here all year, just didn’t have the luck to go along with it.”

Garcia, who led a race-high 71 laps, dropped to 10th place. Chase Purdy won the Sunoco Rookie of the Year in the K&N Pro Series East despite a last-place finish in the race at Dover.

Rob Turkington was in the hunt for the Drivers' Title up to final race but was hit by a competitor

But not so, despite the aforementioned setbacks. The "long view" is that Team BMW won the Dunlop MSA British Touring Car Championship (BTCC) Manufacturers title, and the Team title, along with Colin Turkington finishing second in Drivers’ standings, and the still-recovering Rob Collard, who sat out the final races, still finished fifth among drivers.

Colin Turkington had positive words for the entire Team BMW operation after the race: “It’s a great achievement by the whole team to win the Teams’ and Manufacturers’ titles today and everybody should be congratulated for the hard work they’ve put in over the season.”

Rob Turkington drove from 15th to win in the second-to-last race of the year

WSR left F3 at the end of the 1995 season as the most successful team in the history of the series, both in terms of race victories and titles. The decision was made to apply its tremendous capabilities to the British Touring Car Championship.

For 2007, the team switched to BMW, and today runs BMW 125i M Sport models that were designed, engineered, and constructed in the WSR shops (unlike many other series around the world where BMW provides the team with a turn-key race car). With 2017’s double-title success, WSR has now won an incredible six outright BTCC crowns in the past four years.

Team Principal Dick Bennetts summed up the season: “Every member of the team can be very proud of what we’ve achieved and we are also extremely thankful to our partners, technical suppliers, and sponsors, without whom none of this would have been possible.”

And as one of those technical suppliers, K&N is proud to have been part of this championship effort and congratulate Dick, Colin, Rob, and the entire WSR team for an excellent season. To quote WSR from its Twitter post: Let’s do it again in 2018.

Bo Butner took the win at Maple Grove Raceway In Pennsylvania

A group of Gold Star Moms, whose children have died in combat fighting for the United States military, placed decals with the names of their children on Butner’s car. He counted them over the weekend. There were 27 decals on his car. “I needed them all,” Butner said. “It didn’t hurt.”

After the races, the Gold Star Moms joined a contingent that visited Washington, D.C. the Sunday of the races at Maple Grove Raceway. Butner said the pressure of producing for the Gold Star Moms was greater than any of the races over the weekend. “That was the most pressure,” Butner said. “I haven’t done a lot military-wise in my life. I have some military in my family. But when you actually get to meet the moms and they’re there and they’re hugging you and you’re saying, ‘Yeah, I’m going to get your kids in the winner’s circle.’”

Butner was true to his words. He won at Maple Grove. It was his fourth career win in NHRA Pro Stock, all coming in 2017. It also put him in first place in the Pro Stock standings, 41 points ahead of Anderson, after two races into the six-race Countdown to the Championship playoffs. But winning for the Gold Star Moms trumped taking the lead in the Pro Stock standings. “I am glad we can do that for them,” Butner said. “I’m sure they’re all very happy and I’m sure I will hear from each and every one of them. It’s a good cause and we’ll do something else with them I’m sure.”

Pro Stock Driver Bo Butner takes home his fourth Wally in Pro Stock at Maple Grove Racway

“He’s learning the car,” Butner said. “I’m pretty sure he knows a lot about the car. Way more than Jason. He’s been great. He’s learning. It’s great to have him.

“The KB team is strong and we showed it today and through qualifying.” Butner talked about winning the NHRA Pro Stock championship at the beginning of the season. He entered the season without a win in Pro Stock. He has four now and his team is clicking at the right time.

“It’s kind of hard for me to grasp,” Butner said. “Four more races left. We have to do our job.

“Very fortunate for those three days in a row. It’s tough. You can win from 16 here. A lot of people have done it. I didn’t do the best job driving, but I did just good enough. I’ll take that.”
