Description:
The K&N 57-2581 FIPK air intake system replaces the restrictive factory air filter and air intake housing in specific Ford F150 V8 models. K&N 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 chrome topped K&N high-flow air filter and a heat shield that installs into the lower air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, crank case vent hose and EVAP hose. The oversized cone shaped 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 a screwdriver, ratchet set and several wrenches.

The K&N 57-2581 Air Intake fits some Ford F150 models. See vehicle applications link for details.
