The K&N 57-3029 FIPK air intake system replaces the restrictive factory air filter and air box. K&N intakes are designed to dramatically reduce intake restriction and improve 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. The 57-3029 air intake comes with a large, round chrome topped K&N high-flow air filter assembly that installs onto the throttle body within the previous air cleaner space. Air is directed through the air filter into the engine's throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are simply three wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
