Big waste of time and money.

They don't do anything for SFI(sequential fuel injection) engines.

Worthless piece of crap.

Throttle body spacers are all hype unless you run WOT near redline. At high rpm the increased manifold volume can raise a few more horsepower but only on an engine that is built toward high rpm power. Even for a motor like that you can only evpect 1-2% increase. It comes at the expense of decreased low and mid rpm throttle response. They are absolutely not worth the money on a cost vs. benefit basis.
