Great intake for the money, was missing a couple bolts but that's usually expected, easy enough to go find more. Sounds great and can tell it pulls a lot of air. I got the sealed version and it snugged up nicely to the fender well.

good product

Great intake, not to loud at idle, but comes to life when you crack the throttle.

This stage 2 cold air intake has awaken my GMC Serria. It was easy to install that gas mileage is a bonus on long trips. I will recommend this air filter to GMC Sierra owners.

I went with this intake because of all the great reviews and research I did before making the investment. The primary reason I purchased the CAI was for the possibility of improved fuel economy. After about three tanks I have noticed a marginal increase (aprox 1-2mpg) in my humble opinion that is well worth the price and not to mention the more aggressive sound. Auto anything has lived up to their reputation and I will certainly use them in the future!

Product is good. Saw immediate results in power and that all important sound. Makes the Tahoe sound a little meaner. Installation is a little tricky since descriptions are a little vague concerning taking off push clips. Actually helps not to have outside clamp on reducing coupler when attaching to filter housing. Slides on easier that way. Second aFe intake. Definitely worth it. Chevy does say having a non stock cold air intake violates the emmissions warranty so keep the stock intake incase you have future issues and need to swap it back for warranty servicing.

Better off line response, at highway speeds makes engine a bit louder but the extra 2mpg is worth it

Overall fitment was good, product replaced restrictive factory intake. Not a real noticable power increase except at higher RPMs, but when getting on the throttle hard the intake really growls with the AFE. Product is of good quality, dry filter is great and it looks nice under the hood. Only noticed issue was the filter box did not fit the stock holes from the stock box. Only 3 of the 4 screws would fit the stock holes. Good product and very happy with price.
