As far as the throttle body spacers with spiral grooves that supposedly make more power and torque, you would be better off using a smooth bore spacer instead because the air can't spin anyway due to the throttle blade being in the way. I have heard from some people that using the spiral grooved spacers will make a whistling noise. Overall a spiral spacer will not make more power than a smooth spacer, and if anything it will create more turbulence, which you don't want!
Ok -- for those of you that are running TB spacers --- what brands are you using, and approx what did you pay for them?
I'm looking to do some power upgrades and intake/exhaust are the first things I'm going for.

I installed my street & performance tb spacer over a month ago now. It is spiral cut, produces an annoyng whistle, 1-2 mpg less mileage on the highway on my last 1,900km trip, slightly increased throttle response, but not worth the money IMO. I bought mine used off a guy who said the same thing locally for $70 cdn vs $125 new, just so I could see what all the hype is about.

someome on ZR2.com is selling his own for $50, the are a smooth super clean looking aluminum that he builds with this own machine. The have some grooves inside but the pitch (thats what you call it right?) is almost straight up and down. If you have an FIPK these will NOT wistle

I'm running the Helix Power tower I'll have to check the file and see what it's cost was (more than $50)
IMO, it does one thing that I felt was an improvement....raise the TB 1" (which was an advantage after the BL)
Another reason that I used the spiraled spacer was to aid in mixing of the (restricted) EGR gasses. After installation of the CFM throttle blade and being unable to eliminate the EGR system entirely, I felt that this might help.
It does whistle at midrange mild accelleration (turbo/blower like sound), no change to mileage or performance.
