    Default throttle body spacers

    Have a 99 silverado 5.3L. Anyone have any luck with theses spacers. Do they really work? Do they really get maybe 2 miles more per gallon. Looked at poweraid and others. SOme helix the air into the engine, some do not. Which are better. Please help.

    I have installed them on 2 vehicles I own and I was impressed with increased performance in both cases. There are not a lot of bolt-on performance parts for your application so every bit helps. Exhaust, cold air intake, programmer, and the TB spacer is about all you can play with.
