The K&N 77-1559KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Jeep Liberty models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-1559KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory air temperature sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points requiring commonly available tools to do the job. Some K&N 77 series air intakes are not legal for sale or 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 for vehicle applications and specific CARB status for each vehicle and air intake.

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.
