Grimmspeed Mazdaspeed3 Throttle body and Intake manifold fitment?

[Incdalton]

Does the Grimmspeed Intake Manifold and Throttle Body for the Mazdaspeed 3/6 fit the 2.0L mazda 3?
Both are ported and polished.

No.

The port and polish on the TB by Grimmspeed is a service, you send in your TB and they pnp it for you. They will do the mz3 TBs for the same price.

Damn about intake manifold :/
But, thanks for the help. If I did this PnP, how much of an honest gain would I get out of it? Basically, is it worth it?

You'll probably notice the difference in throttle response, but as far as numbers I doubt much more than a few hp in your power band. I may do this in combo with the thermal gasket to reduce heat, cooler air into the engine.
