Designer plug wire sets deliver highly visible styling and race-inspired performance. ✨ These precut kits come with plug and coil boots plus terminals already installed for fast, accurate installation.

  • Boots and wires are molded from extra-high-temperature silicone for protection up to 600°F. 🔥
  • Spiro-Pro core offers up to ten times the conductivity of standard carbon-core wire for stronger spark transfer.
  • Low resistance design runs cooler and lasts three to four times longer than carbon-core alternatives.
  • Engineered for electronic ignitions but fully compatible with point-type systems.
  • Made in the USA. 🇺🇸

Whether you’re doing a restoration or upgrading for performance and reliability, these plug wires make installation simple and deliver durable, long-lasting results. ⚙️
