throttle body spacers

don't believe there's a thread on this, was looking on AM's website and came across the airaid poweraid throttle body spacer. claims to increase mpg, low end throttle response, and it also says it produces a nice whistle sound, for $130 it doesn't seem like a terrible idea. does anybody know anything about these? if they work? if the sound improves even with an aftermarket exhaust?

I've always been under the assumption that TB spacers are a waste of money on port injected engines because of what they do. Great for carbs and TBI where the air and fuel are mixed at the same place. I see a lot of people running them on mustangs for some reason.

Only real benefit I've seen on these is allowing the usage of the 80mm throttle body without having to trim the fins in the v6 intake manifold. But you then need to modify the 80mm and have it tuned.

Spacers don't do anything on our cars. On a carburetor car, where the air and fuel are mixed before the cylinder it does make a difference. On our cars, the fuel and air are mixed in the cylinder and the spacer doesn't make a difference.

Think about it, if it really made a difference, why not just get a "pringles" can and really add a spacer? The 1/2" move of the throttle body isn't doing anything.

thanks for your input guys. I've been researching throughout the day, seems like a waste of money.

Could also be called a wallet spacer. That's where you money you spent used to be. No real benefit on our 3.7.

It could be a nice place to tap and hide the lines for a dry nitrous system. Other than that.... Well, everyone else has covered the answer.

I knew it wouldn't make any performance difference but I was interested a while back for the sound. I think I was hoping for a GT500 supercharger-ish sound (don't give me crap, you guy all think about that too) but the videos I've seen are closer to a sleeping man with a true "whistler".

that's what caught my attention when i saw it on AM's website, lol. I was intrigued, then they claimed better throttle response and gas mileage and i thought, why not? glad i came here before i made any dumb decisions throwing my money away, lol
