During porting of the intake manifold we bore out the runners making them a larger, more consistent diameter, and we also polish down all of the oem casting marks. The OEM Intake Manifold to Engine Head connection has a big step which impedes flow, we port the Intake Manifold runners so it gets rid of the big step and increases air flow quality into the engine head.
Feel like adding the bling factor with function?...add our optional ceramic coating as shown in picture. Price is for porting only, please select coating option on the bottom if wanted. You must take all wires/hoses/fuel lines/etc off of the intake manifold before sending it in. If you fail to do this we may charge you for the labor it takes a tech to disassemble everything.
