Increase Your Horsepower With K&N's Air Intake

The 57-Series Generation II Air Intake (aka FIPK) is K&N's ultimate performance product for your Ford F150. The engineers at K&N designed this performance intake to boost your horsepower by as much as 10%. Adding a cold-air intake is a perfect way to get some easy power and performance gains for your truck. The 57-Series intake dramatically reduces intake restriction as it smooths and straightens air flow, allowing your truck's engine to inhale a larger amount of air than the restrictive OEM stock 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 4.6L V6.

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.

50-State Legal: This air filter meets the California Air Resource Board (CARB) regulations, making this modification street legal and ensures it is allowed for emissions testing. The CARB # is D-269-37.

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

Free Retunes for Life! Free Custom Re-Tune Program: While K&N's Cold Air Intake doesn't require custom tuning, its performance is greatly enhanced with one of our 5-Star Custom Tunes which will also qualify you for our Lifetime Tunes Program where you can receive free re-tunes for the life of your truck on products that you purchase from Stage 3 Motorsports!
