This was easy to install on a 99 GMC Sierra with a 5.3. The butt dyno says it gave the truck mower power. Still waiting on the evidence of gas saving. I have had it on the truck for about a week.

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

Well the intake works great with the throttle spacer snd the programmer much more horsepower then stock has better throttle response and really didni help the fuel milage at all .
