MSD molds their most popular distributor caps in-house. This cap is injection molded from DuPont Rynite material and features spark plug-style terminals. The terminals offer improved locking connections and the Rynite material is extremely strong with excellent dielectric properties. Plus, most caps have an optional wire retainer that is supplied with these caps to lock the wires in place.
Includes a girdle for retaining the wires to the cap. MSD has used this new design on many distributors built since the summer of 2002. Has HEI-Type terminals, rather than socket-type. Can be used in place of the older design.

- If you are upgrading from a points socket style cap you will need to change your boots and terminals.
