Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series air intakes come with K&N's Million Mile Limited Warranty. K&N 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). Some 77 Series Air Intakes are not legal for use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website vehicle parts search for specific CARB status.

I am sending you a testimonial for a product of yours I recently installed.

Hello

I just recently installed your 77 series intake kit on my 2009 Jeep Liberty Sport 4x4 and what a difference it has made. The 3.7 v6 had decent power but I got your kit because I heard your filters and performance kits gave great results.

This 77 series kit gave the engine new life to it and even though it was only 10hp, this kit helps the engine breath and perform much better. It didn't take me very long to install because I am working as an apprentice mechanic so it took about 40 minutes and it was worth the time! Also I was averaging 490km per tank and this kit brought it up to 540km per tank, which is not too bad for a Jeep.

My next mod is gonna be a lift kit and off road tires.

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.
