Description
Stock spark plug wires degrade under heat and age, causing misfires, poor fuel economy, and reduced ignition performance. SUMAX Spiro-Pro wires deliver superior conductivity and thermal stability, keeping your ignition system firing reliably lap after lap. Purpose-built for both electronic and points-style ignitions, these U.S.-made wires are the upgrade that pays dividends in consistency and longevity.
