1974-81 Pontiac-Built V8 HEI 8mm StreeThunder Spark Plug Wire Set

Features & Benefits

8mm StreeThunder wire sets feature a 500 ohm per foot resistance conductor wrapped in durable silicone blend double layer jacketing for heat protection, strength, and longevity. They are the top choice amongst car enthusiasts with heat protection up to 600° Fahrenheit and 65,000 volts of dielectric strength.

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.
