The K&N 57-1545 Air Intake fits some Jeep Commander, and Jeep Grand Cherokee models. See vehicle applications link for details.
The K&N 57-1545 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Jeep Grand Cherokee and Commander models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Jeep’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 57-1545 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 air intake assembly accommodates the factory vacuum reservoir vacuum line 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 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 57-1545 Air Intake Product Reviews

Wednesday, June 22, 2016 - Part 57-1545
The filter does provide more horsepower, I'm very happy with it. I'm not happy with the lack of parts identification. Horrible, I had look at black and white pictures and try to figure out how to assemble. The nuts,bolts and washers were not labeled. I had to put it together then take it apart it and use the other bolts. The instructions were not specific to a 2007.

After reading and watching videos, I decided to buy this kit...glad I did! I can't believe the difference it makes...throttle response and gas mileage have improved as well as overall power...great buy you won't regret it...only downfall, the instructions aren't the best. But overall, I'm thrilled with my CAI.

This is on my 05 Grand Cherokee 3.7L. I love the gains this system give me very happy. I have had K&N filters on just about every car and truck I have owned and will put them on all the cars and trucks I get from now on. I tell all my friends to get them for their rides that they will fell the POWER gain and it will sound good too. I was going to order a new filter for my system so I could get a free hat but it's only been on for about half a year don't think I have hit that million mile mark yet. Thank for such a GREAT product keep up the good work. Loyal customer.
