MSD Super Conductor 8.5mm Spark Plug Wire Set - GM

The MSD Super Conductor spark plug wire set for GM applications is a custom-fit, bolt-on ignition wire (also called spark plug cables or ignition leads). It is built for strong spark delivery and reliable performance on street, truck, off-road and racing engines. Each set is made for the specific GM application listed.

Key Features:

• 8.5mm Super Conductor construction: a helically wound copper alloy conductor gives very low resistance, in the range of 40-50 ohms per wire.
• EMI suppression: the wire winds the conductor around a ferromagnetic core. This acts as a choke that keeps electromagnetic interference inside the wire, so it does not disturb other vehicle electronics.
• Heat and abrasion resistant sleeve: a proprietary blend of silicone and synthetic material resists high heat, abrasion and tearing.
• Silicone boots: multi-angle spark plug boots help the wires fit and route cleanly.
• Dual crimp terminals: one crimp grips the wire sleeve and a separate crimp grips the conductor, for a secure electrical connection.
• Precut and custom fit: wires are cut to exact lengths for the make and model listed, so installation is a simple bolt-on.

MSD is a long-standing name in performance ignition systems. Super Conductor wires pair low resistance with interference protection, so they suit anyone upgrading a GM ignition system for dependable performance and a clean-looking engine bay.
