K&N Air Induction Kits
Manufacturer of the World's Best Air Filters

K&N air induction systems replace your vehicle's restrictive factory air filter and air intake housing. K&N induction kits are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our induction kits are relatively easy to install using tools commonly available (see installation instructions).
