MSD Ignition Spark Plug Wire Set (MPN: 31609)

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 optimal performance in various automotive applications. This pre-assembled wire set utilizes a copper alloy conductor that ensures a resistance of less than 50 Ohms per foot, allowing maximum energy transfer to the spark plug for efficient ignition of the air/fuel mixture. The wire is encased in a durable outer sleeve made from a proprietary compound, providing resistance to high temperatures and abrasion, which enhances longevity and reliability.

Incorporating a ferro-magnetic impregnated center core, this wire set effectively suppresses electromagnetic interference (EMI), making it suitable for high-performance engines. The design includes 90-degree spark plug boots and socket-style distributor boots, ensuring a secure fit and optimal connectivity. Additionally, the conductor core is reinforced with DuPont Kevlar material, increasing tensile strength and durability under demanding conditions.

With its advanced construction and materials, the MSD Ignition Spark Plug Wire Set is engineered to deliver superior spark performance and reliability, making it a valuable addition to any performance-oriented vehicle.
