Throttle Body Spacer Question

2373 Views 16 Replies 10 Participants Last post by  primetime
I was just wondering what exactly the throttle body spacer does.
It claims it gives 2-4 mpg as well as 5 hp....any truth behind this?

If anybody has purchased one, what are your feelings about it?

To be painfully honest, there is no noticable difference between TBS's. I have the Airraid(Poweraid), and besides the "whistle" at different RPM's there isn't really a difference between the available TBS's that are on the market. Pick one and go for it. If you don't mind a little noise at/around 1500RPM then the TBS is for you. I personally like the extra noise along with the Volant CAI and Banks Monster exhaust...The beastie sounds MEAN!!!
