K&N 100-8576 4” tall carbon fiber air box
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.
