2003 Chevy Avalanch 5.3

Reviewed By Steven T (Garnet Valley, PA) Reviewed for a 2003 Chevy Avalanche —1/22/2008 4:13 PM

This went on OK but needed to ask some questions and Jet Power was closed and since I had things off already I had to keep going. It has a whisle but not all the time and I just turn-up my Sirius. Too soon to tell if its saving me on my gas but I do feel a dif in 2 and 3rd gear. The instruction need to have more detail like the K&N intake I put on.

I have a 2003 Chevy avalanche with a 3" lift on it. When i put the lift on it I lost some power. As soon as I hooked this up to it, i got all the power back plus a lot more. I prob. got 16HP on it and 17 Ft. Lbs. It works great, Could not be anymore happy.

aFe Silver Bullet Throttle Body Spacers Reviews

Overall Pleased

Reviewed By Richard C (Harrisburg, PA) Reviewed for a 2008 Chevy Avalanche —6/29/2012 7:09 AM

I have had it installed for just over a week now and I definitely can tell the improved throttle response. I haven't seen any improved MPG. As for horsepower, I have this installed with the aFe cold air intake and overall I feel more horsepower, but not sure which item really provided the additional horsepower. I purchased because I wanted more power for towing and better MPG. The better MPG is yet to be realized, but I would still recommend to others given the relatively low cost and increased horsepower.
