No way $100.00! Ebay has them all day for $30.00 I just ordered one and haven't put it on yet. Some people like them and others say they are a waste.

Yup

100 bucks ? Way way too much


Like already noted .. some people like them.. some don't

Main problem seems to be .. anything taller than what hmm 1/2 inch I believe .. and you may end up having linkage problems

TGO welcomes you!

TBI spacers increase the plenum volume of your intake which is desirable to make more power. You always want more plenum volume. However, these spacers offer little volume increase at the expense of linkage problems and high prices. You are better off getting an injector pod spacer and using that $100 on something else.

I would only use a TBI spacer as a tuning tool and or a way to squeeze out every lost drop of power.

Ebay has them the cheapest at about $10, but Jegs sells them at $20 and TurboCity sells them at $29. It's your choice, they're really all the same thing and are all the same height (1/4").
