The K&N 57 Series FIPK 57-3021-1 air intake system replaces your vehicle’s 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. The 57-3021-1 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. The placement allows air to be directed past the mass air sensor through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain.
