Has anybody tried this yet?

I only found one thread (with a good explanation by scheherazade of how it works) but I have yet to see anybody actually try it out yet.

general consensus is: its a waste of money.

You can be the first to write a review on it. I've heard that there is some truth to the science behind it... but in reality it would have to be a lot more substantial to be evident or produce the claims AFE makes.

It's your money - waste it as you feel fit, but this is definitely a waste!

my '89 K1500 pickup loved the throttle body spacer I put on it, this car, I have no idea.

thats only because the throttle body was on top of the intake manifiold and this spacer just raised the throttle body up away from the heat a little! same as the 5.0 efi spacers, but on these applications i think its a waste of money

I have it.
I didn't do a review on it because there isn't that much to review.
The thing that I like about it is that it's supposed to put turbulence on the air that is entering the intake manifold.
IMO, there is too much air going to the 2-5 cylinders and not enough for cylinders 1 and 6.

i know what your sayin in theory, but with the piston pulling air in when on its downstroke and the boost from the turbos pressurizing the manifold, i doubt spacer or not that there is a shortage of air going to those cylinders, and the 2-5 cylinders can only fill up so much no matter what, so you really cant have too much air going into them.

You're right. It didn't really come out right.
All I'm syaing is that cylinders 1 and 6 don't get the same air flow as 2-5 and this is supposed to help with that.

do you think it would be good to drill and tap for a meth nozzle? or is it too close to the throttle plate? that would be the only use i can see for it

Way too close to the manifold. Not enough time to vaporize and distribute evenly.

cool thanks, thats what i figured, but i had to ask to be sure

Under boost, the spacer should do nothing - in a non boosted car it is different and will have more of an effect.

The nice thing about air is that it's a compressible fluid. So it's very unlikely that you can see a significant pressure differential between runners. It's not like a common fuel rail situation where you have non-compressable flui and require pulsation dampers to deal with pressure differences. Why exactly do you believe that 1 and 6 don't get the same airflow? Individual cylinder EGT testing suggests otherwise.

WOW... some great info here... thanks alot guys

With this said... using no boost, would a Bigger Diameter Throttle Body (i.e. Dinan) with this Spacer make a significant (or noticable) upgrade?
