Description
Factory spark plug wires degrade under heat and high RPM conditions, causing misfires, rough idle, and poor engine response. SUMAX's Spiro-Pro core technology delivers 10 times the conductivity of standard carbon-core wires, keeping your ignition system running cooler and more reliably. With boots rated to 600°F and a lifespan three to four times longer than conventional wires, this is the upgrade that pays for itself through dependability and performance.
