MSD Cam Sync Plug

SKU: MSD-85XXX Categories: ,


Multiple Applications Available


MSD’s cam sync plugs are the perfect solution when running an aftermarket sequential EFI system with coil-per-cylinder ignition. The cam sync plug installs in place of a traditional distributor, providing a hall-effect cam sync signal needed for the EFI system to reference the # 1 cylinder. For wet sump applications, the plug also drives the oil pump. MSD’s cam syncs are plug and play with Holley EFI systems and can easily interface with most aftermarket EFI systems.
  • Built-in L.E.D. makes set-up and indexing quick and easy
  • Plug-and-play with Holley EFI and compatible with other aftermarket EFI systems requiring a cam sync signal
  • CNC billet housing with black anodized cap provide good looks and excellent durability
  • Ford Big Block version is supplied with a bronze distributor gear
