Designer plug wire sets come in distinctive, highly visible colors and are precut with plug and coil boots and terminals already installed. 🔌

Boots and wires are made from extra-high-temperature silicone, providing protection up to 600°F for reliable performance under heat. 🔥

The Spiro-Pro core delivers up to ten times the conductivity of standard carbon-core wires for stronger, more consistent spark delivery.

Low resistance design helps the wires run cooler and last three to four times longer than carbon-core alternatives, reducing maintenance needs.

Engineered for electronic ignitions but fully compatible with point-type systems, these wires offer versatile fit and dependable operation.

Manufactured in the USA to demanding standards for durability and performance. 🇺🇸
