DESCRIPTION
MSD Super Conductor 8.5mm Red Spark Plug Wire Set
These are a direct replacement wire set built to exceed OEM specifications. Super Conductor wires are built with high-temp boots and an 8.5mm jacket that protects against high heat, abrasion, and common automotive chemicals and fluids to provide years of trouble-free performance. Inside, a low resistance copper alloy conductor is spiral wound around a Ferro-magnetic core; this combination produces high-performance wires that transfer maximum spark energy to the spark plug while preventing EMI from interfering with on-board electronics. MSD Super Conductor spark plug wires are backed by a one-year warranty from the original date of purchase.
