K&N 97-04 Ford F150/Expedition / Lincoln Navigator V8-4.6/5.4L Performance Intake Kit

The K&N 57-2541 FIPK air intake system replaces 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 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 57-2541 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. Air is directed past the mass air sensor and 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, air bypass valve, air temperature sensor and crank case vent hose. The oversized conical 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 the existing factory mounting points. The only tools needed are a screwdriver, ratchet set and several wrenches in most cases. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty. K&N's easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow. This power gaining air intake comes with K&N's famous million mile limited warranty.
