RE: Throttle Body Spacers
The JEt TB Spacer is not like the others. It has a helical cut on the inside to cause the air to spin and it does limit the whistling. I had it installed for over a year and thoroughly loved. It does not increase HP but it does provide more torque, slightly better gas mileage and elimnates the throttle body lag.
The only reason I removed it was because the Ford Plenum cover would not fit with the TB spacer installed. After removing the TB spacers, I missed it immediaely. At first I kept stalling in first. I get used to giving the car more gas in first gear. I've also noticed my gas mileage has gone down slightly; about 1-2 MPG.
A throttle body spacer works on the burneulli pinciple. The berneulli principle states that that as the speed of a moving fluid increases, the pressure within the fluid decreases. Conversely, by increasing the pressure on the liquid (in this case air) the speed of the liquid will increase. The throttle body provides a slightly smaller tunnel for the air to flow through. The reduced diameter of the TB spacer increases the pressure and forces the air to move faster. The volume of the air is not changed, thus no tune is needed.
The following link has a cool animation that allows you to modify the diameter of a pipe and lets you observe the simulated effects of the liquid flowing through it.

RE: Throttle Body Spacers
i haven't gotten anything yet, but MMR looks pretty good to me.. their intake says it adds 35RWHP* with their tune.. the tb spacer is supposed to add 10hp/tq.. is getting a throttle body just for those that have a lot of mods.. i've heard its too much air or something if you don't have many mods.. mines still stock but i want to do a few things.. i've heard many good things about C&L but can't decide between that and the MMR intake.. haven't really seen much talk about it =/

RE: Throttle Body Spacers
TBs and TBspacers are the two most worthless mods for a N/A 3V. (The spacer is worthless regardless.) I'd look more toward pulleys, intakes and tunes if I were you. They are good, cost effective mods for N/A.
