MSD 8.5mm Red Super Conductor Spark Plug Wire 50ft 34029

MSD Super Conductor spark plug wire delivers the low-resistance performance your ignition system demands, with minimal voltage drop and efficient energy transfer to the spark plugs. The helically wound copper alloy conductor and ferro-magnetic core work together to eliminate electromagnetic interference, keeping your engine firing clean and consistent across the RPM range. At 40-50 ohms per foot, this wire maintains the spark intensity your high-performance build requires, whether you're running a stock engine or a heavily modified racing platform.

The 50-foot bulk length gives you the flexibility to custom-cut and route wires for your specific engine bay layout, making this ideal for custom fabrications, engine swaps, and competition builds. MSD's proprietary silicone and synthetic sleeve resists extreme heat, abrasion, and fuel contact, ensuring long-term reliability in demanding conditions.
