K&N FIPK Air Intake System | 2011-2014 Ford Mustang GT (57-2578) K&N Filters

FIPK Cold Air Intake System by K&N

The K&N 57-2578 FIPK air intake system replaces the restrictive factory air filter and air intake tubing while retaining the factory air box on specific Ford Mustang GT models.

K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow for a guaranteed horsepower gain. This allows your engine to inhale a larger amount of air than the factory air filter and air intake assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-2578 air intake comes with a replacement K&N high-flow air filter and an aerodynamically engineered intake tube that easily connects to your vehicle’s factory air box and throttle body. The air filter can be used for up to 50,000 miles before servicing is needed depending on driving conditions. This air intake system is designed for quick and easy installation with commonly available tools. This air intake meets California emission standards and is legal for use in all 50 states.
