The out of the box MSD runners and port alignment leaves a lot to be desired. We port the entry transition from the throttle body flange to the plenum, as well as the manifold runners. The manifold is completely disassembled for this. Runner Taper is verified and any casting flaws from the manifold production are removed.
*We recommend taking the top off the intake, clean thoroughly, and test fit on your engine to validate port alignment prior to final installation *

Great service
Manifold looks great and quick turn around. I can’t wait to get it installed.
The porting on this MSD looks very even throughout all the runners and the throttle body opening. I can’t stop showing people until I get it put on my car. Nothing but quality from GPI!
Great prep work!
Great work on the porting I would highly recommend this option when buying the MSD manifold.
