1963-79 MOPAR Big Block HEI except HEMI 10.4mm 409 Series Spark Plug Wire Set (Available in 2 Colors)

Features & Benefits

10.4mm 409 Series wire sets provide continuous heat protection up to 600° Fahrenheit and 102,000 volts of dielectric strength making them a great choice for drag, circle track, off road and other high heat applications.

Custom Wires are designed to replicate your OE wire set. Each wire is cut to length and booted to match OE wires. Lower resistance will get more fire to your spark plugs, increased horsepower and torque, and improved fuel mileage.
