The K&N 57-2576 Air Intake fits some Ford F250 Super Duty, Ford F350 Super Duty, Ford F450 Super Duty, and Ford F550 Super Duty models. See vehicle applications link for details.
The K&N 57-2576 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Super Duty pickups. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Ford’s 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 57-2576 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous 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, filter minder 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 existing factory mounting points. The tools needed are a screwdriver, a ratchet set and several 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.

Easy to install, truck sounds amazing and the instant power gain was great. Highly recommend installing anything K&N on any vehicle you own.

This is a well designed, easy to install, attribute to the engine. It's basically bolt on HP. Helped with the additional weight I was pulling near the trucks max capacity. Thanks K&N.

Good product. The allen wrench included did not fit the small mushroom head screws. Would be nice if the wrench fit both sizes of screws in the kit. Other than that no issues. I am not a mechanical person so I was a little apprehensive about ordering this item. But everything went together smoothly. Paper instructions were good. Especially liked the video instructions I could refer to online.
