A sister product to our 57 Series FIPK, our 63 Series AirCharger® Air Intake Systems are guaranteed to increase horsepower and come with K&N's Million Mile Limited Warranty. K&N air intake systems replace 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 vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). These Air Intakes cannot be sold in California. They are not legal for use in California or other states adopting California emission standards.[MORE]

 My experience with both installation and performance of my K&N filter was fantastic. The parts/directions were easy to use and I got the filter on in under an hour. It sounds excellent, and in the three weeks I've had it on I've already noticed an improvement in fuel consumption. I would definitely recommend this filter to anyone else with an F-150.

 Great product, couldn't be more pleased. Easy install, and you can feel the difference.

 Excellent product. Sounds great and performs great. The video provided on the site was excellent and I venture to say saved me a great deal of time. Thanks.
