Does anybody know what a throtle body spacer is, does, cost, worth it?

 

i'm not big on performance fuel injection but i never did see any reason for the spacer in the t'body.

 

ok just askin, i don't know, i'm just looking for some more horse power with not spending as much money.

 

Those are mutually exclusive desires. Most of the things you see advertised to increase hp are either an outright fraud (Vornado) or offer a modest increase but at an rpm that you will rarely see unless you into stoplite drags (CAIs & throttle spacers).
