About this product
This MSD 31389 Super Conductor 8.5MM Spark Plug Wire Set is the ultimate performance wire for 1965-1978 Ford 351C-400 engines with a socket style distributor cap. These wires use a helically wound copper alloy conductor with only 40-50 ohms resistance per foot of wire.
As a result, 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.
