The K&N 57-1506-2 Air Intake fits some Jeep Grand Cherokee models. See vehicle applications link for details.
The K&N 57-1506-2 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Jeep Grand Cherokee models. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Grand 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 57-1506-2 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 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, a ratchet 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 57-1506-2 Air Intake Product Reviews

Monday, May 1, 2017 - Part 57-1506-2
Install is not hard, but the instructions are hard to follow and the pictures with the instructions are almost useless, black and white, small picture, low resolution. A video would've been way more helpful or at least an online link to the instructions where each picture could be clicked on to see it better than the little 2 black and white photographs accompanying the instructions. Also, one part was wrong. Supposed to be a No.60 hose clamp, mine was a No.52 and, of course, too small. Called customer service, they were great and shipped me out one the next day. I actually noticed the increase in hp after it was installed. Overall, this would've been a 5 star review except for the poor install instructions.

When I got my first 1997 Jeep Grand Cherokee I had put this kit on (57-1506-2) and loved it so much! I just got another Grand Cherokee now and for sure am going to be doing this to it as well! Great products and some of the best intakes I have ever used! I work for a performance shop here in Huntsville and we sell and install ALOT of K&N intakes and everyone loves them!!!!

I ordered the intake for my 1998 5.9L Jeep Grand Cherokee, my friends have sworn by them for years but they all drive imports. I ordered it and was skeptical at first to be honest. But After reading the reviews of the intake system for my Jeep I was sold. The reviews where extremely helpful. After installing the intake, immediately I noticed better throttle response and acceleration and it sounds cool as well.  It was a very sturdy and well made, definitely worth the bucks.
