Performance and Longevity, Engineered by K&N

K&N High-Flow Original Lifetime Engine Air Filter is engineered to boost engine performance by increasing airflow up to 50%, delivering a more responsive feel when you press the accelerator. The result can be a smoother throttle response and a more confident driving experience.

Designed with four layers of premium cotton gauze and a tack-coating, the filter creates an intricate mesh that helps trap contaminants while allowing clean air to reach the engine. This combination is built to work with your factory air box, so installation is quick and non-destructive.
