The Generation II FIPK® is K&N's ultimate performance product, designed to increase power by as much as 10%. Most FIPK's are street legal in all 50 US states and come with a Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount 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 intake kits are relatively easy to install using tools commonly available.

To maintain airflow efficiency, use Recharger Filter Care Service Kit.
