Description:

K&N High Performance Air Intake System for 3.7L Engines allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. This 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 an aerodynamically engineered intake tube into the engines throttle body for a guaranteed power gain. The over-sized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. It replaces the restrictive factory air filter and air intake housing in some Jeep Liberty models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points.
