Overview

K&N 57 Series FIPK Cold Air Intake Kits

The K&N 57-2503 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 57-2503 air intake comes with a vent hose and chrome topped K&N high-flow air filter that mounts in the previous air box space. Air is directed through dual intake tubes that lead into the engine’s throttle body for a guaranteed power gain. The oversized, oval tapered cone-shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake usually installs in about 90 minutes and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

The K&N 57-2503 Air Intake fits some Ford Bronco, Ford F Super Duty, Ford F150, Ford F250, and Ford F350 models. See vehicle applications link for details.
