MSD Ignition Spark Plug Wire Set (MPN: 31323)

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 pre-assembled 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 capped with dual crimp terminals for secure connections, and the set includes both straight spark plug boots and 90-degree distributor boots with HEI style terminals. The proprietary outer sleeve provides additional protection against wear and tear, making this wire set a reliable choice for performance enthusiasts.

With a total of eight wires, this spark plug wire set is engineered to deliver superior spark and reliability. The use of DuPont Kevlar material in the conductor core enhances tensile strength, further contributing to the longevity of the product. This wire set is an essential component for those looking to enhance their vehicle's ignition system and overall performance.
