Save your money, the only throttle bodies they work well (if at all) are ones that are fuel injected in the throttle body, all Magnums are multi-port injected. Which means that there is a fuel injecter for every cylinder, the spacer won't help because the whole idea behind it is to get a better mixture of air/fuel by make the intake runner longer and that little swirl design is supposed to make it move faster, B.S.! A lot of people have made the mistake of buying one and all report no gains in power or gas milage.

I agree with Kris on the spacer comments as well. I've Dyno and Track tested the Poweraid "Helix Bore" TB Spacer and there was NO gains in MPG or HP. They work great for TBI or carbs, but not on MPI. If you want to get better airflow down the TB and into the heads, have the manifold extrude honed and polish the runners.
Plus, the factory manifolds have a very restrictive design in the plenum. Even if the air was "swirled", by the time it makes it to the head, the effect is gone. (I modified mine and gained about 8HP and a a noticeable improvement from 2500rpm on up.)
