This is a great product! Easy to install, uses the base of the existing air filter housing. Instructions are very clear, you just need a bit of mechanical aptitude and basic tools. Sounds great and looks great too!

I installed this in about 35 minutes. Super easy instructions and parts. This thing is unreal. My girlfriend asked if I got an exhaust system. Lol it really gurgles.

Instantly improved throttle response, gas mileage is still to be determined. Makes the engine noise resonate with a powerful growl when you step on it. No cab noise difference cruising down the highway. Easy install, great product.

the K&N intake works great and has a nice rumble at high RPMs. You can notice the HP gains when you take off. Installation should take 30 minutes or so if you have the required tools in hand. If you like a quiet engine this product is not for you.

best buy and price

So easy to install, less then 45 minutes. Love the sound and averaged at least 1 mile per gallon better on the highway.

Very easy to install. Finished in about 30 minutes. Sounds great. Definitely worth the money. Great sound when you step on it. Haven't noticed much of a difference in gas mileage, however, I only had my truck for 2 weeks before I threw this thing on it.
