It was easy to install and also had a great appearance for my 99 Sierra. Overall, I was impressed with how easy it was to install and also the performance I got out of my truck right after installation! A+

I was very pleased to see the outstanding results in this intake system. The sound and performance from a simple bolt on are well worth the bucks for this product. You really feel that extra push at the top of the tach. (4900-5200). I would do business with Auto Anything anytime. --Nate

I've had this installed for a couple weeks now, and as soon as I drove my truck afterwards I noticed a difference. Better throttle response, more power, my truck has really opened up now. As far as gas mileage I'm not sure, since I installed this with the Spectre Throttle Body Spacer as well, though it definitely didn't make it worse. Truck also shifts more smoothly, especially on the highway, gives the truck a nice growl. Installation took me maybe an hour, anyone can do it.
