throttle body spacers

[thasianhh]

i know i'm gonna get a lot of opinions on this.....but do throttle body spacers really work on fuel injected motors?

barely. if there is any gain, its a negligible amount

i added a 2" spacer, a 3" flow master system, and a k&n filter- gained quite a bit actually- don't notice so much in town, but i just drove back from south carolina(to wisconsin) and noticed a huge difference-

and..... that is also due to the fact that you added exhaust and air flow modifications. the spacer by itself wouldnt have much affect
