6875, Throttle boby spacer?

Do they make one for for our cars? If so would it do any good? I've seen them for camaros, mustangs, and for full size trucks.
It's supposed to increase the velocity of the air entering the intake manifold.

I think the only cars that these work for are carb guys and throttle body injection guys. We are neither, using port injection. For the carb guys, the spacer can reduce heat transfer to the carb (keep fuel cooler). For both carb and TB inj, it may help keep the fuel suspended in the air. I couldn't imagine it helping us.

The vast majority of TB spacers I've seen are for late model 5.0L pushrod Mustangs with MPFI. Dont know the physics of it all but they use em. Keep in mind the V8s F.I. lower manifolds are pretty simular to V8 carb manifolds if that means anything.

But it would make sense to make a manifold spacer. Instead of porting your manifold, you could port match from the existing manifold to the cylinder head with the spacer.

Velocity is key. That will aid in volume of air as well.
