Reviews for K&N 57-1514-1 Fuel Injection Performance Air Intake Kit for 97-06 Jeep Wrangler TJ & Unlimited with 4.0L Engine

Works great, improved MPG for a Jeep.

Directions could be a bit more descriptive but other than that it’s a great intake.

Have installed on each of 3 TJ’s. Great addition

Great fit, easy install.everything you would expect from K&N

LOVE this! it took about an hour to install, maybe more because I took my time, I did kind of jump around the instructions, just to pre assemble some components before I started taking out the factory air intake. once installed I DID feel a BIG difference in the acceleration and (with out trying to hot rod it all the time) it had increased my fuel efficiency by roughly 4 MPG

Improved performance and does help with gas mileage. Easy install !!!'

Easy to install. It provides a throaty sound and gives it extra pep!

looks great sounds great just installed it so waiting to calculate gas mileage, easy installation.

Works great. Fits well. Install was fairly easy if your handy.

Overall great system. I noticed a minor difference in horsepower and gas mileage. Easy installation and instructions were spot on.
