Features & Benefits

8mm Spiro Pro wire sets are for street & strip, off road, street rods, and custom cars. 8mm Spiro Pro wires are engineered to deliver superior performance with unsurpassed quality. They are the top choice amongst racers and enthusiasts alike with heat protection up to 600° Fahrenheit and 65,000 volts of dielectric strength.
