I've seen everybody advertise Throttle Body Spacer's having gains of 5-10hp. I wonder what actually are the gains, anyone had experience with them and what are the gains with a CAI or TB? Thought about this b/c if the gains are right $100 seems like one hell of a pricce for those gains or close to them!

Thanx ahead of time

I've heard they're worthless.

 

There are about a dozen threadson TB spacers across various forums including this one. Score TB spacers 0 Worthless 12.

 

Thanx guys, saved me about $100+
