This K&N AirCharger air intake system replaces the restrictive factory air filter and air intake housing. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. This air intake comes with a K&N high-flow air filter which is protected from the elements with an enclosed filter housing. Air is directed through a custom-molded intake tube into the engine's throttle body for a guaranteed power gain. The oversized cone shaped air filter is washable and reusable. This air intake is relatively easy to install usually in 90 minutes or less. The tools needed are two torx screwdrivers (T30 and T15), a flat blade screwdriver, a wrench, and a ratchet set. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
