MSD 31239 Universal Super Conductor 8.5MM Spark Plug Wire Set

This MSD 31239 Universal Super Conductor 8.5MM Spark Plug Wire Set is the ultimate performance wire for engines with late model HEI “spark plug top” distributor caps! This wire set comes with the spark plug terminal and boot installed, with the other end open. Distributor cap boots and terminals are included, so you can custom tailor the length of each wire.

These wires use a helically wound copper alloy conductor with only 40-50 ohms resistance per foot of wire. Less resistance means more energy to the spark plug to ignite the air/fuel mixture!

Each foot of finished wire features 40 feet of this conductor for high EMI suppression as well as superior conductivity! This highly effective “choke” keeps the Electro Magnetic Interference inside the wire as well as away from other electronics.

This combination is encased in a heavy-duty sleeve that withstands abrasion as well as high temperatures. Stainless steel Dual Crimp snap lock terminals as well as high temperature boots ensure you have the best wire available!
