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.
