Many race car and engine builders struggle to find an air filtration solution for injector stacks. The filter must be large enough to flow enough air, must securely mount to prevent damage during a race, and yet be small enough to not obstruct the driver’s view. K&N took each of these variables into consideration when developing a new carbon fiber air box at slightly over 4 inches tall.
K&N’s new 100-8576 air box was developed in carbon fiber to attach to four inline injector stacks. Simply measure and cut holes for your 2” – 2 5/8” diameter Hilborn, Kinsler, Engler, or similar injector stacks in the carbon fiber base of the K&N air box, slip the base over the stacks, and then attach the filter top using the provided hardware.
The K&N filter element is made of multiple layers of cotton treated with K&N air filter oil. This combination offers high airflow with little restriction, while at the same time providing excellent filtration to keep your engine running strong the entire race. After the race, the filter can be cleaned and reoiled using K&N air filter cleaning products and restored to like-new condition for the next race.
K&N’s new 100-8576 carbon fiber air box can be purchased through any K&N authorized dealer. To find a dealer in your area, visit our dealer search page.

Thomas Fletcher raced Stock class in Pomona
The NHRA champion also drove a second car in the Competition Eliminator class.
Fletcher lost in the final round. “I went to Pomona hoping to split and get that
first win light,” said the sportsman racer. “I won Super Stock first and that
was awesome. The competition eliminator was another issue. It broke a rocker arm
going into the momentum at half-track. Unfortunately that’s the way it goes.
That car gets better with every race but we’re just short of knocking on the
door to the winners circle.”
Fletcher has 14 consecutive wins since November 2007 in Super Stock at the
Pomona facility. It was also his fourth national event win in a row. He lists
wins in Richmond, Vegas, Pomona and Pomona. Fletcher's 18-year-old son is
starting his career.
“My son Thomas raced the Stock class in Pomona,” said Fletcher.
“Unfortunately he was stranded at JFK airport because of bad weather and missed
his practice runs. He was only able to make one qualifying pass before the first
round of eliminations and lost first round. The good news is Thomas and I will
race next week in Phoenix.”
Fletcher uses K&N Stubstack (85-0200) on the competition eliminator and K&N oil
filters (HP-3002) on all three vehicles. “K&N oil filters are ingenious,” said
Fletcher. The nut on the bottom makes it easy to change. My engines outlast and
outperform thanks to K&N.”

With a stylish new body and more interior room, the 2008 to 2015 Scion xB is a grown-up version of the first generation xB. Scion also added the 2.4L engine from the tC sports coupe to the list of the xB's features. K&N has designed and released a new performance intake system for the 2008 to 2015 Scion xB which uncovers an additional 9.06 horsepower at 5026 RPM hidden behind the xB's factory intake.
K&N part number 69-8613TS features a mandrel bent aluminum intake tube, which is powdercoated silver for a low maintenance metallic finish. The mandrel bent tube ensures incoming air has a smooth, unrestricted path to the engine. The factory fresh air duct is retained, and routes outside air to the inside of a powdercoated steel heat shield, directly toward the K&N air filter. The factory mass airflow sensor is removed from the stock air box, and reinstalled into a CNC machined adaptor on the K&N intake tube. This combination allows the xB's 2.4L engine to breathe more efficiently, resulting in an immediate 9.06 horsepower increase over the factory system, with no other modifications necessary.
The RU-3570 round tapered air filter mounts within the heat shield, and provides virtually unrestricted airflow while providing superior filtration. Multiple layers of K&N's high flow cotton filter media are treated with 0.97 ounces of K&N air filter oil, which traps dirt and dust without sacrificing airflow. The RU-3570 is also washable and reusable, and can go up to 100,000 miles before cleaning.
The 69-8613TS installs easily in 90 minutes or less, and requires only a socket set, pliers, wrenches, and a flat blade screwdriver. A photo illustrated instruction sheet is included to guide you through each step. The entire cold air intake system is covered by K&N's Million Mile Limited Warranty.
K&N air intake 69-8613TS fits the following vehicles:
