Reviews: K&N 57 Series Performance Air Intake Kits

It was easy to install.So easy you dont even need instructions. Noticed hp gain. It has a nice roar to it when you have to give it some gas

Awsome make jeep sound better

It has only been on a week but it seems the jeep has more spunk or at least it sounds that way. It took me about 2 1/2 hours to install but this is the first one I have installed and it would be much less time if I were to do it again. I'm looking forward to more HP and miles per gallon.

Nice clean installation, easy to follow instructions. great fit and quality

Worked great, definitely helped out my 4l TJ running at higher altitudes.

Installed the intake and immediately felt a difference. I know most people say you don't really notice with these but on my AWD Mountaineer with tires 3in over factory and 157k miles...it feels new again! I can pass again on the highway and feels like a whole new truck through town

4wheelparts is good to go. This K&N intake is great . Easy install and instant improvement in power, SOUND! and gas mileage.

Easy to install instructions easy to read and go along with

Love the sound in accelerating felt a lil more HP.

Makes the turbo scream and lets the truck breathe so much better

Best purchase I have made for my jeep. It instantly made my jeep drive and handle much better.
