GMS GT/GT500 twin 62mm Throttle Body up for sale. Never installed and doesn't come with the spacer. GMS sells the spacer for $85 + shipping but I can get whoever buys this the number for someone who sells the spacers $85 shipped. GMS's price for the throttle body and spacer is $400 looking for $300 obo. Thanks

 

how much power will this add?

 

I don't think it adds all that much power....just improves throttle response dramatically.

 

GMS claims it adds anywhere from 11hp-22hp but yea I think it mostly helps for throttle response and even some economy gains.
