MSD Ignition Spark Plug Wire Set (MPN: 31779)

High-performance spark plug wire set with low resistance and EMI suppression.

The MSD Ignition Spark Plug Wire Set features an 8.5 millimeter diameter and is designed for high-performance applications. This wire set utilizes a copper alloy conductor with a resistance of less than 50 Ohms per foot, ensuring maximum energy transfer to the spark plug for optimal ignition of the air/fuel mixture. The helix-wound design incorporates a ferro-magnetic impregnated center core that effectively suppresses electromagnetic interference, enhancing overall engine performance.

Constructed from silicone and synthetic materials, the wire set is built to withstand high temperatures and abrasion, ensuring durability in demanding environments. Each wire is pre-assembled with straight spark plug boots and 90-degree distributor boots equipped with HEI style terminals, facilitating easy installation. The proprietary outer sleeve provides additional protection, making this wire set suitable for both street and racing applications.

With a total of eight wires included, this spark plug wire set is engineered to deliver superior spark and reliability. The combination of advanced materials and design features makes it a valuable addition to any performance engine setup.
