MSD 8.5mm Red Super Conductor Spark Plug Wire Bulk 100' 34049

If you're building a custom ignition system or replacing worn spark plug wires, you need a conductor that delivers consistent spark energy without signal loss. MSD's Super Conductor design combines low-resistance copper alloy with an EMI-suppressing ferro-magnetic core, ensuring efficient energy transfer to your plugs. This 100-foot bulk spool gives you the flexibility to run custom lengths while the silicone sleeve handles extreme underhood temperatures and abrasion.

Whether you're tuning a street machine or running a dedicated track car, reliable spark plug wires are non-negotiable for ignition performance. The 40-50 ohm-per-foot resistance spec keeps voltage drop minimal, translating to stronger, more consistent combustion. MSD's proven Super Conductor technology has earned its place in professional racing and serious builds for good reason—it works.
