Not much if anything to complain about. I just wanted to get on here and say I have seen alot of people make note that it's loud. Well it has a loud sound as you start it up cold. Once the vehicle warms up it goes away. It all has to do with the choke . After engine warms up its all good. And even when it's not it's not a bad sound.

Amazing product made with amazing quality. I can hear the engine roar a lot more. Power wise I can't really feel it much, probably because it's only an extra 6 horsepower but I guess it does its job like it said

Put this in a 2005 Jeep liberty 3.7 L. Install took about 90 minutes as promised with very clear instructions. I do nothing but highway driving with my new job and was getting 16.7mpg. First tank after install was 17.8 (with a little unnecessary accelerations) 2nd tank was 18.8. The vehicle is definably more responsive at low end rpm. With my current milage I will hit breakeven on this product in 11 months if gas stays at $2.00/ gallon.

This intake brought my 11 year old engine to life. From a stop, flooring it will send you back in your seat, which isn't bad for a liberty. The sound is amazing, it has a deep growl and sounds like a muscle car around 4000 rpm. For fuel efficiency I've only noticed a slight improvement, but then again I've been driving around with the pedal on the floor cause it sounds amazing. Very easy to install, anyone that has a socket wrench and screwdriver can do it. I'll get one for every vehicle I have!

This item was purchased for my 3.7L Limited Jeep Liberty / Cherokee, and is a very good product, does exactly what it says in the blurb (better possibly). Easily enough fitted with noticeable performance increase. Excellent!

Another well-made FIPK. Instructions are clear, kit is complete, and build quality is good. Fits and performs well.The only complaint I have is the placement of the IAT in the new intake tube - it is a bit of a stretch to get the factory harness to plug into it.

Love this product. Took me 90 mins to install like directions says. Added more horsepower and changed gears smoothly. Also it added 4 miles to the gallon. Two minor problems is the oxygen sensor positioning could be a little closer to the housing so it would not stretch the wiring and when engine is started cold it makes a really loud sound of air sucking. Once the engine is idling correctly the sound is perfect. I would recommend this product to every Liberty owner. Should have came stock.

This was an excellent purchase. I can't comment on overall MPG increase, as I had this installed at the same time as a Jet Performance Chip, but with a 3" lift, and 31+" tires, I got an MPG increase of 4-6 MPG across the board (with the intake and the chip). The Jeep sounds entirely different (definitely meaner and deeper), especially when you get on it a bit. Highly recommend this!
