MSD Ignition Spark Plug Wire Set (MPN: 31659)

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 wires are encased in a durable outer sleeve that provides resistance to high temperatures and abrasion. Each wire is pre-assembled and includes 90-degree spark plug boots and distributor boots with socket-style terminals, facilitating easy installation. The use of DuPont Kevlar material in the conductor core increases tensile strength, making these wires robust and reliable for demanding conditions.

This spark plug wire set is ideal for those seeking to improve ignition efficiency and engine responsiveness. With features such as RFI suppression and a heavy-duty design, the MSD Ignition Spark Plug Wire Set is engineered to meet the needs of performance enthusiasts.
