Direct replacement 8.5 mm Super Conductor spark plug wire set.

Part Number: 31639

Available in red and black, 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 now available for the Ford 6.2L V8 found under the hood of SVT Raptors, and select Super Duty models. MSD Super Conductor spark plug wires are backed by a one-year warranty from the original date of purchase.
