A sister product to our 57 Series FIPK, our 63 Series AirCharger® Air Intake Systems are guaranteed to increase horsepower. 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.

I love your products! I purchase mine for my Scion FR-S, and I can say this is the best simple performance upgrade I ever made! I feel the difference in power right away. I even purchased another one for my Jeep Liberty! Great product, thank you!

2011 Jeep Liberty Renegade 3.7L, 4x4, trail rated has a real world city driving increase of about 1.6 mpg on the uphill / downhill area driven. Haven't taken it out on the freeway for a long trip yet but if the city driving is any indication, I would expect highway mpg to possibly increase by about 3+ mpg. Jeep KKs & JKs do not get good mileage because of the non-aerodynamic (flat) front end, low gearing and extra weight from under chassis skid plates so this is a pleasant surprise. Low end acceleration has a felt increase, especially from a standing start on a 5% or more uphill grade, without sacrificing the increased mileage. Because of the increased engine performance, the transmission shifts faster into the next higher gear and holds the gear longer under load. I would buy another K&N air filter for any vehicle I own.
