Pretty happy with the product... it comes complete with everything you need , fairly easy to install. As for performance side it gives a little boost and faster throttle response, don't expect night and day difference and also makes it better with higher grade and better quality gas . Shipping was fast , it helped probably cause it came from California and so was the rebate check. All and all , for the money, I'm really happy with it and love the sound as well.

Fabulous Addition

This cold air intake made the biggest difference in performance I have seen with similar installations on other engines (4. 6, and 8 cyl.) from other auto manufacturers. There is improved bottom end, mid-range and high end performance as well as improved gas mileage (8%). This intake is well worth the investment.

So far so good. Seems to have more power, sounds pretty potent when you get on it. Not sure about gas mileage yet. Happy thus far.

Wow.. Increase in MPH and throttle response..

Installed in my 2008 Jeep Wrangler Sahara Unlimited with 189,000 original miles on it. I have always said my only complaint was this vehicle was underpowered. Not any more! Instant, aggressively loud acceleration to speeds Jeep Wranglers are just not supposed to go. So much fun stomping it down while passing other cars (especially Jeeps). Easy to install (I'm no mechanic) and well worth the money. You can't beat K&N quality. My son is now installing one on his 2006 Mustang.

Incredible. Nothing short of what was advertised. Easy installation (about 90 min) and wow what a difference. Throttle response is incredible. I can really feel and hear the difference when I open it up. Gas mileage has Increased slughtly but I still need to change the OEM exhaust and a computer chip. I think that will give me everything I'm looking for. Even still the K&N 57 cold air intake by itself has made a huge improvement. Very satisfied customer. Thanks, Jason Bush Lutz, Fl

I've been driving my jeep as a daily commuter and for over a year and my jeep did not have the power that I needed until I put this CAI. It's totally a difference of night and day. The response is AWESOME, sounds SUPERB and looks equally nice. Highly recommend, can't tell if it helps on gas but it's a jeep- I was looking at having more responsive power of keeping up with traffic and not having to drop it back to 4th gear when climbing a hill!!!!

This item was a birthday gift for my Grandson. He was delighted with it. Directions were easy to follow and installation wasn't complicated. He thinks it is really helping his gas mileage.

Great Product

Bought this CAI for my 2010 4 door Wrangler to help produce a little more power. So far I'm very happy with the results. Noticeably more pull especially when getting on the highway and the whistle at 2K rpms is awesome!

K&N makes a fantastic product. Put this on my jeep and sounds great when you get in the gas. Big improvement on acceleration...real smooth and I have gained about 1 mile per gallon on fuel. Highly recommend
