MSD 8.5mm Super Conductor Spark Plug Wire Set

Description

Product Overview

The MSD 8.5mm Super Conductor Spark Plug Wire Set is engineered for high‑performance automotive applications. Featuring a proprietary heat‑resistant plastic outer sleeve and a Dupont Kevlar‑reinforced conductor core, the set delivers less than 50 ohms per foot for optimal spark energy. Each foot of wire contains forty feet of tightly wound conductor, providing exceptional EMI suppression. The ferro‑magnetic impregnated core acts as an effective choke, reducing electrical noise and improving ignition reliability. Dimensions are 3 × 11 × 8 inches, weighing 2 lb, and the set includes a single black 8.5 mm wire ready for installation.

Usage

Designed for both street‑driven and race‑track engines, this wire set excels in environments with high heat and vibration. Ideal for performance enthusiasts, mechanics, and professional racers, it fits standard spark plug connectors and can be routed under exhaust manifolds thanks to its flexible silicone design. The durable outer sleeve resists abrasion, making it suitable for long‑term daily driving as well as aggressive track sessions.
