MSD Firewall Feed-Thru

Product images may differ from actual product appearance.

If you have your coil mounted in the passenger compartment, you need the Firewall Feed-Thru. The Feed-Thru offers a half inch of spark isolation through a rynite mold to ensure that the spark gets to the distributor cap instead of jumping to ground at the firewall. A brass rod is surrounded by an injection molded rynite and nylon housing to form a spark isolating path through the firewall. Spark plug style terminals are used for strong Coil Wire connections. Mounts in a 1'' diameter hole with supplied hardware.
