This spacer has a mild gain. It can only be used on a stock throttle body. It will work.

Looks much better than the factory tube - would have given it 5 stars on appearance but was scuffed from rubbing on the box. I really liked the sound tube delete option - really cleaned up the engine bay. No noticeable gains in performance - actually lost 1/10 of a mile per gallon. Was hoping to get rid of the lag in throttling in stop and go traffic but this still persists. So for me it was all about eye candy.....
