Bullit Intake

[ModularGT]

Sorry for my stupidity.

I see alot of bullit intakes and some are port and polished and some are extrude honed (sp).
What is the difference and which is better?

I am looking into getting a new intake and appreciate all your help.

Thank you,
Kyle

Extrude is the only way to go but some what pricey. They shoot abrasive putty through all the curves and crevases of a fuel injected intake like no porter can unless he splits the intake and welds it back together like they did to the 5.0 intakes back in the late '80's. It also evens out the flow from port to port automaticaly.
