Travis Miller won the first NASCAR K&N Pro Series East race of his career at South Boston Speedway

Miller, who started in the second row, passed rookie Chase Purdy for the lead on lap 59 after the only restart of the race. There was one caution for four laps, from laps 55-58.

"I wasn’t quite sure how it was going to work there," Miller said. "That was probably the winning move on our part."

Chase Cabre won the pole and led for the first 19 laps of the race. Purdy took the lead on lap 20 and was out front for 39 laps. Cabre fell back and finished in seventh place. Purdy crossed the finish line in second place.

"He was definitely faster than me at the end of the race," Miller said about Purdy. "He drove me really good and I actually cut him off once or twice. I definitely appreciate him driving me clean even after I did that. All in all it was a good race."

Purdy posted his first top five finish and second top 10 in five K&N Pro Series East races.

"That was down to the wire," Purdy said. "Hats off to my crew. The work they do in the shop all week doesn’t compare to what you see here. They work their butts off. They give me a fast race car and that was just hard racing right there."

Travis Miller led 40 laps of the NASCAR K&N Pro Series East race at South Boston Speedway

"That was the game changer right there," Miller said. "It was really hard to pass on the bottom here. That’s what won us the race, that restart."

Todd Gilliland, the 2016 K&N Pro Series West champion, finished third. Dillon Bassett was fourth, followed by Harrison Burton in fifth.

Burton took a 14-point lead over Gilliland in the K&N Pro Series East race after the first race at South Boston Speedway. Purdy was third, 24 points behind Burton.

K&N cold air intakes are designed to feed your engine more air thus giving it more power

The paper OEM filter and corrugated air tube that likely came with your truck from the factory worked well for what the engineers needed. However, enthusiasts are often left scratching their heads and asking, “who designed it like this?” Unfortunately, engineers are under a lot of constraints when manufacturing a vehicle. Everything from time and money limitations to keeping the sound levels and power numbers at the correct levels often plague engineers during the build. That is why companies like K&N Engineering offer solutions like cold air intakes.

The install of a K&N cold air intake takes around 90 minutes and can be done with common hand tools

Another part of the cold air intake equation, besides getting more air into the engine, is the quality of the air. As stated before, these systems typically have a heatshield or air box to separate the air filter from the engine bay. The air in the engine bay is quite warm, while the outside air is relatively colder. Cold air has more oxygen molecules than warm air. The mass airflow sensor in your vehicle can detect the temperature of the air and inject more or less fuel as necessary.

One of K&N's newest series of cold air intakes is the Blackhawk Induction line of intakes

K&N offers several different cold air intakes for vehicles depending on individual needs. These vary from a traditional oiled cotton media to a non-oiled synthetic media. The choice is yours. So if you need a boost in power and the ability to filter out dirt and dust before it reaches your engine, check out K&N to see all the intakes and other products they have to offer.

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.
