what is the difference between the tfs streetburner intake manifolds, and the tfs track heat intake manifolds. And if the throttle body bore diamater is 75mm does that mean i should get a 75mm throttle body? And what about the basic operating rpm range, if i were to purchase one what should i look for there, what improvments in power would i see after intalling this?

It depends on your use for the car. Does it have stock heads? The TB opening should be 70 or 75mm in dia.

Give us a little more info on the use of the car, and maybe we will be able to help you out a little better.

The car is stock except for gears and a flowmaster exhaust.

Track heat has shorter runners to give you a little bit more high end hp while scarificing some low end torque. Dont expect any significant gains, headsmake all the difference on the 5.0
