THE ORIGINAL RED AIR FILTER SINCE 1969

There’s a reason top racers trust K&N® to protect their trophy trucks in the Baja 1000, premium racecars in 24 Hours of Le Mans, million-dollar NASCAR engines, and high-horsepower dragsters: K&N® air filters let airflow in and keep dirt out. Designed for the racetrack—made for your vehicle. Layered, oiled cotton media provides up to 50% more airflow than traditional paper air filters, potentially increasing horsepower. The durable filter frame and media are built to last the entire lifespan of your vehicle and are backed by a 10-Year/Million Mile Limited Warranty.
