Poweraid Throttle body spacer

I bought the Poweraid Throttle body spacer used off the zr2.com UBB
This thing is supposed to create a swirling of the incoming intake air
charge (the Vortec engines are supposed to do this from the factory),
whatever it does do seems to create a small WOT poser increase.
I know the added intake volume helps WOT, and this unit proves it.

Would I buy this mod again?
Probably, but not new, I would have to find a used one like I did with this one.
