K&N replaces the original intake assembly with an all-new air intake design. The new system draws air from under the OE fresh air inlet through a K&N High-Flow Air Filter (RC-5165) that never needs to be replaced.

A powder coated steel heat shield mounts in place of the stock airbox and protects the chrome top cone shaped K&N air filter from engine heat. Air travels through a black textured powder coated aluminum tube and a 90-degree angled silicone hose that is attached to the throttle body.

It takes less than 90 minutes to install this cold air intake with simple hand tools. K&N Performance Intake Systems are designed to improve engine performance along with under the hood visual appeal.

Early on it looked as if he might have come in first instead of second. Allard started the 30 lap main on the outside of the second row in his K&N Filters No. 0. He quickly moved into third place and by the second lap he slid under Brent Kaeding to move into second. He was on the back bumper of leader Roger Crockett by lap five.

With only seven laps to go, it looked as if Allard had the opening he needed. Kaeding was strung out on the high side of turn two and had a car directly in front of him. Allard drove right below Kaeding, but another car moved to the bottom and blocked him. The Defending King of California could not make up the ground he lost and settled for second place, just a couple of car lengths behind Kaeding.

“We lost the power steering pump during the race and I had a hard time steering,” said Allard. “We’ll take a second place, my crew worked hard.”

Jonathan Allard and Williams Motorsports will be back in action tonight with the K&N Filters No. 0 as the 36th annual Dirt Cup at Skagit Speedway begins.

"We use K&N Engineering Oil and Air Filters along with K&N’s Carbon Fiber Air Box,” said Allard. “K&N makes the best products, the oil and air filters are easy to use and maintain. We just wash, assemble and race and we never have to worry about performance.”
