The K&N 77-series air intake system is designed with both style and performance in mind

The 2016-2017 Land Cruiser utilizes Toyota’s well-proven full-time four-wheel-drive system. Choice of either the high- or low-range are made selected by turning a console-mounted dial. The center mechanical differential is a Torsen torque-sensing unit set to a 40/60 front-to-rear torque split, but has the ability to self-adjust if more power is needed at one end or the other. Both brake and throttle are controlled by Toyota’s Active Traction, if the situation demands. Meanwhile the driver has his or her choice of settings (Multi-Terrain, Crawl, Downhill Assist, Mogul, and Hill-Start Assist) to optimize performance for the terrain being traversed.

While the Toyota Land Cruiser’s 5.7L V8 produces 381 horsepower and 401 lb-ft of torque, one has to recall that the motor is pulling around nearly three tons of mass. That’s part of the Land Cruiser’s strength, but also one of its weaknesses. Go back to the turn of the century and Chevrolet was producing 350 horsepower out of the technically inferior 5.7L LS1 engine.

The heat shield isolates the filter from underhood heat, allowing only cold air to flow to the motor

Cool, fresh air first enters a chrome-topped RF-1044 K&N high-flow air filter positioned within a heat shield that installs into the space of the factory air box. Much of the performance increase can be attributed to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media which offers greater surface area and thus less resistance than traditional filters but provides outstanding engine protection.

Engine protection is provided by a multi-layered cotton material, which filters out fine particles of dirt and dust that could damage your engine, to ensure a long engine life. Each design is verified through K&N’s in-house filtration testing lab, which adheres to ISO 5011 standards, ensuring that K&N filters provide high airflow without putting engine protection at risk.

Everything needed to install your new K&N 77-series performance air intake is included in the box

The intake tube of a K&N cold air intake significantly reduces restriction to incoming air flow over the stock item, as well as calms power-robbing turbulence. Air passes through an aerodynamically-verified polished 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 intake system 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 YA-1515 is designed for excellent filtration and added airflow

Anytime you are dealing with a limited displacement motor like the 149.7 cc single in the Yamaha, a boost in performance is a welcome thing. That is the design goal of the K&N YA-1515.

The YA-1515 features K&N’s free-flowing cotton gauze filter media that increases airflow to the engine. That boost in intake volume often results in crisper throttle response and quicker acceleration.

The same pleated, oiled, cotton gauze filter material that provides ample airflow, also filters that air very efficiently. K&N’s in-house filter testing resulted in an impressive estimated overall filtration efficiency of over 98% with the YA-1515.

The YA-1515 comes pre-oiled and ready to install right out of the box

A couple of the most appealing features of the Yamaha T150 are the bike’s low-maintenance requirements and environmental friendliness. The washable and reusable nature of the YA-1515 enhances these traits even more.

Cleaning is made simple with the K&N 99-5000 filter recharge kit, and K&N’s Million-Mile Limited Warranty means you will not need to buy another filter for the life of your Yamaha.

When you combine the YA-1515’s excellent filtration, reusability, and the possibility for a bit more power, it emerges as the clear air filtration choice for your Yamaha T150. Check the application list below, and consult K&N’s easy-to-navigate online application tool.

Adler battled to the third position in both races in Chandler, Arizona before having truck issues

The series' marquee Pro4 division drivers took little time in demonstrating just how anxious they were to get back to racing and to put on a spectacular show for the fans in attendance. That first-race adrenaline manifested itself in an abundance of aggressive driving. The first three laps of the race were littered with caution flags and extreme contact. Doing his best to stay free of the carnage, Adler methodically worked his way through the field.

"After a few days here at the track setting up, testing, and then qualifying for the race, these guys were ready to go today," said Adler. "It took us the first three laps just to get a clean start, but when we did, it developed into a great race. There was plenty of beating and banging but that's what Pro4 racing is. This is not a sport for the timid."

Adler's team burned the midnight oil to get his damaged truck back in shape for race two

"We were on a good run and had the speed to finish strong today. Things move quickly out there. We raced hard, made some passes, and moved through the field to put ourselves in a great spot. Then in a moment, the truck has an issue and your race is done."

After a late night, Crew Chief Mike Seat and the 4 Wheel Parts team had the 900-HP Pro4 ready for the second race of the weekend's doubleheader. A solid qualifying effort secured a second row start for Adler. When the flag dropped, a fantastic start resulted in Adler moving into the third spot. With a tightly packed field jostling for position, Adler’s #10 truck made contact with another racer. The contact damaged Adler’s front tire, which would present a serious dilemma just laps later.

Just after the mid-point in the race, Adler was solidly planted in third but was facing a difficult choice. He could opt for a tire change or he could stay on the course and risk potentially catastrophic damage to his truck. Adler elected to pull off the track and into the pits.

Even with a quick return to the track, Adler found himself a lap down to the leaders, a gap that would prove insurmountable. While he finished the event, the result was not indicative of the on-track effort and pace he maintained throughout the day.

Certainly Adler and Team 4 Wheel Parts will be chomping at the bit for the return to Chandler which is scheduled as the site for the season finale. However, there is a lot of racing in various venues before that return will come to fruition.

Ricky Stenhouse Jr celebrating his win at the Geico 400

"This is for all the guys at the shop--we’ve been terrible for a long time," Stenhouse said. "This year, every race, we’re just getting better and better. We knew Talladega was a good race track for us. It’s been a good one in the past.”

The win was an uphill climb for Stenhouse, as he led for the first 13 laps of the race, and did not lead again until the penultimate lap. Stenhouse received 49 points and 5 playoff points. He currently sits in 12th place in the Monster Energy NASCAR Cup Series standings.

“It feels really good to get that first win here” Stenhouse said. “I remember sitting in the bus watching this race and knowing that this is a racetrack that we've had good success at, we've ran well. You know, so close to home. It feels awesome to get the first win here.”

Jamie McMurray finished in second place, 0.95 seconds away from finishing in first, and getting his first win of the season. McMurray was passed by Stenhouse Jr. on the final lap, after passing Kyle Busch in the process.

“Like there's times when you feel like you're going to have a good run and you don't, and then there's other times that it happens,” McMurray said. "So it was a good overall day for us.”

Kyle Busch finished in third place, who led three times for 48 laps. Busch led for a race high 39 straight laps before being passed.

The crash between Chase Elliott and AJ Allmendinger

A crash on lap 169 wrecked 18 of the 38 cars in the race. Chase Elliott tapped the back of AJ Allmendinger’s car, and flipped onto the hood of Joey Logano’s car. The stoppage took 26 minutes to clean up, Busch restarted in first place.

Dale Earnhardt Jr. finished in 22nd place in his last spring race of his career.

Kyle Larson continues to be in first place in the Monster Energy NASCAR Cup Series Standings with 428 points and 7 playoff points. Martin Truex Jr. is in second place with 374 points and 10 playoff points. Brad Keselowski is in third place with 367 points and 11 playoff points.

The next race in the Monster Energy NASCAR Cup Series will be at the Go Bowling 400 at Kansas Speedway.

Kyle Wyman catches air on his way to a top-5 finish at Road Atlanta

Wyman started the weekend impressively by posting the 5th fastest time overall in the qualifying practice sessions. He was less than a tenth off of the factory teams, which is an indication of the blazing one-lap speed of the non-factory rider.

"Friday was a bit of a bumpy start with some mechanical gremlins, but we were still able to put in a time," Wyman said. "Friday's sessions are important because it determines the top 12 riders who will move on to Superpole Saturday morning. Being fifth overall and the top rider after the factory teams is our goal and we were able to accomplish that."

With that goal realized, Wyman moved on to the next phase of his Road Atlanta plan. Wyman had only a 30-minute session Saturday morning before Superpole to dial in a race-setup for the bike which is crucial for the 21-lap races scheduled for Saturday and Sunday. Wyman was able to qualify in 8th position in Superpole, which he viewed as a disappointment after his Superpole performance at the Circuit of the Americas (COTA) in round one.

KWR Racing worked out setup issues for a strong race two

In race one on Saturday, Wyman felt that he and the KWR team shot themselves in the foot with a failed setup decision. That experiment gave Wyman fits in the 21 lap race, especially with the bike's rear end.

"In race one I got off to a bad start and it got worse from there," Wyman said. "From the get-go I felt unsure of the rear end. We tried a different setup for the race compared to qualifying and the bike was just really hard to ride from the first lap. We still were able to hold on to a respectable finish."

While the 9th overall and the 6th in the Superbike class in race one was respectable, Wyman clearly wanted more from the Sunday race. The KWR team went back to the drawing board to come up with setup changes for race two. Those changes proved to be just what Wyman needed to post an incredibly impressive 5th overall on Sunday.

Wyman eyes more progress in the 2017 MotoAmerica Superbike season

Wyman built up a 17-second gap over the 6th place rider by the finish, and chalked up his best ride of 2017.

Setup success and race result progress is the key to the early season rounds, and that’s exactly what KWR Racing experienced over the course of the Road Atlanta race weekend.

"Overall I'm super happy with the result because we made such huge progress over race one, and eclipsed my Superpole time twice during the race,” said Wyman. “My crew has been working so hard to give me a solid bike and they have done a great job. I can't wait to continue at Virginia in a couple weeks where I know we will be strong."

If you own a Yamaha R1 and are looking for the same filters that Kyle trusts on his bike, look no further than K&N. For the 2015-2017 Yamaha R1, K&N makes the YA-1015. And if you track your bike and want a little more airflow, you should check out the YA-1015R.
