Description
Stock spark plug wires degrade under heat and resistance, causing misfires, poor fuel economy, and weak ignition timing. The SUMAX Universal Spark Plug Wire Kit delivers superior conductivity and thermal stability, keeping your ignition system running efficiently across a wider RPM range. With a proven Spiro-Pro core and high-temperature silicone construction, these wires outperform standard carbon-core alternatives by a significant margin—meaning fewer breakdowns and longer intervals between replacements.
