K&N Filters 57-2557 Air Intake 2004-2005 Ford F-150 Pickup

K&N Filters 57-2557 air intake system replace your vehicle's restrictive factory air filter and air intake housing.  The 57 Series Generation II air intake, also referred to as an FIPK®, is K&N's ultimate performance product.

The 57 Series FIPK's are CARB exempt, street legal in all 50 US states.

These kits start out with an extra-large, conical shaped high-flow air filter that captures and holds more dirt and flows more air than a standard K&N OE replacement filter. The filter is attached to a rationally molded HDPE tube that's specifically shaped for your application to reduce turbulence and accelerate airflow into the engine. High-strength adapters connect the K&N 57 Series FIPK intake to the engine for a secure and lasting fit. If you're looking for the best-flowing, best-filtering high performance street legal air intake system, then K&N 57 Series FIPK kits are the way to go!

K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable.
