The K&N 57-1540 Air Intake fits some Jeep Liberty models. See vehicle applications link for details.
The K&N 57-1540 FIPK air intake system 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 allows your Liberty’s 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. The 57-1540 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 engine’s throttle body for a guaranteed power gain. The tube 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 the existing factory mounting points. The tools needed are a screwdriver, socket set, pliers and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-1540 Air Intake Product Reviews

Monday, December 19, 2016 - Part 57-1540
Installed on my 07 Liberty limited. Shipped quickly, no issues, no hidden fees. Which is a godsend (Canadian shopper) since most items shipped always have and extra charge. Very simple and straightforward install. Instructions were clear and easy to follow. The jeep has a nice deep growl now. Noticeable power increase in the midrange and top end.

Wonderful product, couldn't be happier with the K&N quality. Only issue was that I wasn't given the #7 hose clamp that attatches the air filter itself to the tube. I contacted customer service and they helped me find the correct part I needed. I highly recomend this product to others.

Easy to install and a noticeable increase in hp. It also gives my little Jeep a throaty sound. Don't know about gas mileage yet, as I've been a little heavy on the gas pedal since.
