2004-2008 F150 5.4L V8 K&N FIPK Cold Air Intake 57-2556

Increase Your Horsepower With K&N's Air Intake

You can always trust the brilliant intake engineers over at K&N Filters to design something special for your Ford F150, and the 57-Series High-Performance Cold Air Intake Kit does not disappoint. Adding a cold-air intake is a perfect way to get some easy power and performance gains for your truck. The 57-Series intakes are up-gunned versions of K&N's more standard cold air intake kits. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow, allowing your truck's engine to inhale a larger amount of air than the restrictive OEM air filter assembly. On top of their impressive power gains, this Cold Air Intake Kit improves your truck's fuel economy and throttle response, making it one of the most effective upgrades you can grab for your 5.4L V8.

Performance K&N Filter with Heat Shield and Inlet Tube

When they designed their 57-Series kits, K&N dug up the largest air filter that they could possibly fit in place of your truck's factory air box and built the rest of the system around it. The filter is one of K&N's classic high-flow oiled systems that brings in a much larger volume of air than stock along with improved filtration. Along with the filter, each K&N 57-Series kit comes with a full heat shield assembly and a highly efficient inlet tube that works together to promote improved airflow into your ride's engine over the stock air box.

Installation Note: Included in this kit are detailed instructions for a relatively quick and easy installation (takes approximately an hour using standard tools).
