The K&N 57-1521 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Jeep Wrangler models. K&N intakes are designed to dramatically reduce intake restriction as they straighten air flow. This allows your Wrangler’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 57-1521 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 EVAP canister vent line and a replacement silicon crank case vent hose. The oversized 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 and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

I have the Cold Air Intake system on my 1994 Jeep Wrangler 4.0L and love it. More power and it can breath much better than the stock box. Thanks K&N
Chris Vester, North Bend, Oregon
Great Product, it WORKS and is very simple to install. I am always looking to get the best milage and performance out of my wifes Chevy Cruze LTZ/RS (4-cylinder Tubro). Purchased the car new so at 2,500 miles getting 26/27 miles per gal I ordered the K&N System the first tank of gas we got 31 miles per gal now at 7,800 mile we get an average of 29 in town and (42 HWY driving @75MPH). I have K&N systems on all my vechiles - 2002 Jeep Grand Cherokee 4.7 HO/ 2001 F250/V10/ 2001 custome Jeep Wrangler 6 clyinder. GREAT PRODUCT and Great service.
