Info

MSD offers a universal set of 8.5mm Super Conductor plug wires for the Midget racers. These 50 ohms per foot resistance wires are supplied with the coil side’s special locking terminal and boot crimped to the wires. The spark plug side boots and terminals are supplied loose so the wires can be routed and crimped for each application. A special mini-stripper-crimper tool is also supplied.

Note: These low resistance spark plug wires are only applicable to an MSD Midget Coil Pack #8240 ignition system.

Learn how to properly attach new spark plug terminals and boots by reading our tech article. How to Install Spark Plug Wire Ends.

Notes

Locking coil end terminals included.
