MSD 8211 - Firewall Feed Thru, Red

To prevent voltage leaks in passenger compartment mounted coil installations, MSD designed the Firewall Feed-Thru. Molded from Rynite® and nylon, the Firewall Feed-Thru provides 1/2” of insula­tion to ensure that the coil’s spark reaches the distributor.

• Absolutely the best way to route spark plug wire through the firewall
