See vehicle applications link for details. 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 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.� � Product Specifications� �� � Estimated Horsepower Gain 13.12 HP @ 4562 RPM Replacement Filter RC-5046 Air Filter Color Red Air Filter Material Cotton Gauze Air Filter Outlet Shape Round Clamps Included 8 Clamp Material Stainless Steel Clamp Style Regular CARB EO Number D-269-37 Couplers Included 3 Type Gen II Product Style 57 Series FIPK Air Filter Height 9 in (229 mm) Intake Pipe Color / Finish Black Intake Pipe Material High-Density Polyethylene Street Legal In All US States Yes TUV Approved (Europe) No Weight 13.3 lb (6.1 kg) Air Filter Large End Diameter 7.5 in (191 mm) Product Box Height 12.5 in (318 mm) Product Box Length 18.25 in (464 mm) Product Box Width 18.25 in (464 mm) Mounting Hardware Included Yes Warranty 1,000,000 Miles/10 Year Horsepower gains based on similar vehicle dynamometer test.
