MSD Cam Sync Plugs

The Distributor You Need for Coil-Per-Cylinder Ignition

MSD Cam Sync Plugs are designed to install in place of a traditional distributor when changing to an aftermarket sequential EFI system with coil-per-cylinder ignition. Cam sync plugs provide the hall-effect signal that is needed in order to reference the number 1 cylinder and contain a steel distributor gear. Each Cam Sync is plug-and-play with Holley EFI and most compatible aftermarket EFI systems.
