Designer plug wire sets arrive in distinctive, highly visible colors for easy routing and serviceability. ⚡
Each wire is precut with plug and coil boots and terminals already installed, so installation is straightforward and mess-free.
Boots and wires are molded from extra-high-temperature silicone, providing protection up to 600°F for superior heat resistance.
The Spiro-Pro core delivers up to ten times the conductivity of standard carbon-core wires, producing lower resistance, cooler operation, and three to four times the service life.
They’re engineered for electronic ignitions and also perform well with point-type systems.
