how expensive and how hard are they to install?
do they add a noticeable power difference?
what companies offer them?

i dont want to go all out on my tbi, but if i can upgrade it a little for now, any extra power will help

thanks

 

THere have been so many posts for this. Use the search option at the top right.

 

I heard from somebody i know that the throttle body spacer that you can buy out of the Jegs catalog is junk because i guess the throttle cables are to short when you put it on so it pointless but im sure that you can find a good one or make your cables longer some how.

 

I got mine from CFM technologyies it works mint. they got a ton of tbi stuff.

 

I have used www.turbocity.com to get my TBI parts and they seem to do ok. You can get a spacer from just about anybody but they have all the little stuff that makes a difference. Give them a try they might be able to help.
