I apologize in advance if this has been discussed, I searched and found nothing.

I was looking on Ebay for plenum spacers when I came across a couple listings for throttle body spacers (see below). Does anyone know if this will have any positive effect on performance or MPG? It is cheap enough. I assume it is useless. Thanks...

Sounds a lot like the Turbonator.

 

^^Or the Volcano. I doubt it works. Nothing any good cost $65.

 

Figured it was along those lines...

 

They make a cool whistle tho I have one from poweraid on a 350 not sure if it accually did anything but it def swirls the air

 

No, these spacers (I believe) have straight shot tapped lines into the spacer for Gauges to utilize?? Or atleast thats what I read...

 

dont waste your money with that one you linked. the point of the TBS is to theoretically increase the plenum's air volume. The little angled cuts on that thing you linked is worthless. If you want a TBS just buy this one
