I use a Trick Flow Track Heat, with a set of iron ported and polished gt40's, 70mm t body and spacer, 73 mm mass air, headers, an F303 cam, msd ignition, and 100 shot of nitrous. I LOVE IT. I had a gt40 intake off of an explorer the track heat is a big improvement over that. But like he said depending on what else you have done or will do, and what you intend to do. I agree on the cobra issue, good bang for the buck.
