The K&N 57-1518 Air Intake fits some Jeep Cherokee models. See vehicle applications link for details.
The K&N 57-1518 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Jeep Cherokee pickups models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Cherokee’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 57-1518 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 crank case vent hose. The oversized, tapered 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 and two 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.

Had the Filter kit installed on my 2001 Jeep Cherokee for about 4 months now, so far so good. Definitely better than the stock one that it replaced. Lighter and way less to maintain. Can definitely feel the HP in the lower gears. Would definitely replace all other vehicles with K&N.

You can feel the air hit the engine. Increases horse power and torque just like it promised.

Finding the system I wanted was easy, easy ordering and quick delivery. The parts themselves are very rugged but the packaging was a little scarce and stuff rattled around inside the box. The part that concerned me is that it is such a better deal to go online than pick it up at the 4X4, retailer just down the street from where I live? Who has it in stock. I don't want to bitch too much here because I saved $50.00 and hope to receive an additional $25.00 from a mail-in rebate. But I want to trade with brick and mortar locations because I need them for other things. And I want them to stay open . But, your company ROCKS, has awesome products, you support local racing of all types and I've used your products for years - on everything I have with a motor . Thank you... Jeff

This product lives up to all the hype. I read through many reviews then bit the bullet. Noticable performance increase, in addition to about 1 mpg increase....simple installation...high quality components. Installed in my 2000 Jeep XJ w/ 4.0L. Highly recommend.
