The Custom-Fit Spark Plug Wire Kit delivers reliable ignition performance with race-inspired design and proven electrical technology. 🔧✨

  • Designer plug wire sets come in distinctive, highly visible colors for easy routing and identification.
  • Precut with the plug and coil boots and terminals already installed for quick, accurate installation.
  • Boots and wires are made from extra-high-temperature silicone, offering protection up to 600°F.
  • The Spiro-Pro core provides up to ten times the conductivity of a standard carbon-core wire, ensuring strong spark delivery.
  • Low resistance reduces heat and helps the wires last three to four times longer than carbon-core alternatives.
  • Designed for electronic ignitions but also performs well with point-type systems.
  • Made in the USA.

Perfect for restorations and performance builds, this kit combines durability, ease of installation, and superior electrical performance for dependable starts and smooth running.
