MSD Ignition Spark Plug Wire Set (MPN: 31309)

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 encased in a durable outer sleeve that provides resistance to high temperatures and abrasion. Each wire is pre-assembled with straight spark plug boots and socket-style distributor boots, making installation straightforward. The use of DuPont Kevlar material in the conductor core increases tensile strength, ensuring longevity and reliability under demanding conditions.

This spark plug wire set includes a coil wire and is designed to meet the needs of performance enthusiasts seeking to improve ignition efficiency. With its robust construction and advanced materials, the MSD Ignition Spark Plug Wire Set is engineered to deliver superior performance and durability.
