Chevy Big Block Race Fit 8mm Spiro-Pro White Ceramic Boots Spark Plug Wire Set with Under Headers HEI Fitment

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.

Race Fit wires arrive cut to exact length and fully terminated — boots and terminals installed on both ends, ready to drop straight in. Note that lengths are optimized for the chosen routing path; if you're running a fixed loom or an alternate wire path, fitment may vary. An extra-long coil wire is also included, one end fully prepped and the other left open so you can trim to length and finish with the boot and terminal to your high-performance coil of choice.
