Overview

The MSD 31539 Super Conductor Spark Plug Wire Set is engineered for the unique demands of Ford and Chrysler Hemi style cylinder heads found in Pro Stock racing. These heads feature deeply recessed spark plug tunnels, which the MSD's injection molded tubes are specifically designed to navigate. This is a universal kit, providing extra-long 8.5mm wire, spark plug terminals, and boots pre-installed on one end. The kit also includes distributor cap boots, terminals, and a Mini-Stripper-Crimper, allowing for custom length adjustment to achieve an optimal fit and a clean aesthetic in the engine bay.

Part #: 31539

Routing spark plug wires is an art form. It takes patience and time to route your wires away from the headers, through separators and to the distributor cap. Some wire sets fit perfect, but a lot of people want to build their own so they can route them exactly how they see fit.

Features:

  • Extra long 8.5mm wire so you can cut to your desired length
  • Distributor cap boots and terminals included
  • Includes Mini-Stripper-Crimper

The new Ford and Chrysler Hemi style cylinder heads being used in Pro Stock racing features a long, skinny tunnel to access the spark plug. MSD's injection molded tubes are designed specifically for these hard to reach plugs.
