If you’re looking to build your own 300M coil on plug setup for your DSM then this is the plate for you. Newly redesigned, it is CNC machined from 1/2″ thick 6061 aluminum and the coils are recessed into the plate for a clean professional look. The underside is pocketed out for weight savings. Includes new SS hardware. Please note that you will need to cut off the bolts that are attached to the coils from the factory, and replace them with a nut/bolt combo (not included). Also the rubber boots will need to be trimmed since they are too long to work with the DSM head. We recommend purchasing the coils from rockauto.com, use P/N UF269, the newer AC Delco coils have a different bolt pattern.
