K&N 57-1526 FIPK Cold Air Intake Fuel Injection Perfomance Kit

I live in Colorado, so anything that can be done to help a motor to ingest more air at this altitude is huge! I have a 2002 Jeep Grand Cherokee with the 4.0 liter inline six. I think the biggest help with the 4 speed automatic would be to make it shift better, but so far the K&N intake system has been nice. I dont feel a huge horsepower gain, but unless you supercharge the motor there wont be a massive gain. The sound, however is great! With a cold start, you can here it just sucking in the air. When youre driving and get it up to high rpms it has a very throaty sound(Im sure with an after market exhaust it would sound even better, thats my next addition).

The installation was a breeze. You literally just remove the stock box, put the rubber on top of the heat shield(had to make one cut), bolt down the shield, attach the tube, then the filter and youre done. The only part that took me a minute to figure out, was one bolt that holds the stock box in place has a nut that you have to remove underneath the wheel well. Definitely a faster install than the air intake system we put on my friends 2006 F-250(Not a K&N system).

I would recommend this K&N system, it looks great, sounds great and adds a little more power.

Easy To Install, Looks Nice, Performs AWESOME, Sounds Great, Even Though My Car Was In The Shop For Two Weeks Right After I Put It In Enjoyed Every Minute Of It, Just Got Done Driving With It In And Can NOT Complain At All, Shipped Really Quickly Even Though It Seemed Like They Back Ordered, But Still Took Only 2 Days To Ship!!!!!

The installation of this kit is very easy if the instructions are followed.Overall it took approximately 45 minutes from removing the factory hardware to closing the hood after complete install.You can definitely hear the air being taken in at idle.Almost sounds like a vacumn leak Have driven the Jeep approximately 350 miles and am very pleased.Seems to be a slight increase in fuel mileage and easier throttle response

When I first got it the tube seemed to be made of fragile plastic and felt cheap in my hands. After waisting no time installing it I was impressed with the sound and MPG change (was averaging 21 mpg on highway, but now getting 25-26 mpg!!!) I have not noticed an increase in speed. I did 0-60 in 13 sec and after intalling it I did 13 sec. in same conditions. I recomend it to who ever doesnt want to make a weekly trip to the gas pump.

I own a 2001 Jeep Grand Cherokee I6 and this thing has made a really big difference it makes te car sound and run better i recommend anyone to buy this its worth every penny.

I installed this on my 2004 Grand Cherokee 4.0 which took about 30 minutes. I really didnt expect much but what a difference in response and acceleration. It also sounds pretty cool!!! I highly recommend this product.

I have a '99 Jeep Grand Cherokee Limited and I installed the Air Intake kit and what a difference it made. I can definitely feel a difference in power and the engine even sounds better. I am also experiencing slightly better gas milage.
