Throttle Body Spacer

[Naks]

So I'm aware that there are a bunch of throttle body spacers out there. My question is; do they actually improve performance / mpg? Im looking at the Volant throttle body spacer and want to know if its worth the money (even though its quite cheap).

Thanks!

Waste of money. Spend your money elsewhere

thats what i figured. and from the looks of it, adding 1/3" or so to the throttle body doesn't seem like it would make any significant improvement, if any at all. thanks

I had a helix power tower on my v6 Camry and it made a big difference to me.

I put the same on my Denali but I honestly can't say it made any difference.

The only real way to gauge a difference is when you install with a stock setup. Once you have a intake exhaust tune ect you won't be able to notice any difference.

It does have a nice whistle at low rpm range.

it works on carb engines and the 91-99 TBI motors . . . anything else, it was useless

Questionable on a carbed engine...and completely useless on a vehicle with EFI. Save your money.

ALSo the turbo cyclone insert is useless also. For $100 you can do so much more.
