About us

NAPA® Belden® Edge is a basic manufacturer of premium spark plug wire sets, with three locations in North America. Our highly automated bulk wire facility employs a comprehensive production process that includes everything from custom silicone compounding to continuous vulcanization outer jacketing. In fact we even mold our own wire boots which has allowed our engineers to make improvements to many original equipment design flaws.

Vertical integration assures that NAPA® Belden® Edge product quality, with reduced production costs, is maintained in each step of our process. Working seamlessly with our assembly plant and distribution center, NAPA® Belden® Edge maintains complete quality control from raw material through packaging, so it’s no surprise that we were one of the first wire and cable companies to achieve ISO/TS16949:2002 certification. The result is that NAPA® Belden® Edge customers receive Belden® innovation, quality and value in every NAPA® Belden® Edge wire set they purchase and install.
