Ignition Wire Sets

Superior dielectric and thermal qualities

Factory-original fit, appearance, and performance

World-class chemical and oil resistance

Fit Right, Look Right, and Work Perfectly

Identical OE End Caps

Designed to “click” into place for easy installation and a secure fit. This allows the installer to “feel and hear” that a solid connection has been made, even when the connection is in a difficult-to-see location.

Strong Connections

Through a patented process, the terminals are attached to provide an extremely strong connection ensuring the cable and boot will not separate during removal and installation.

Pre-cut to Exact Lengths

Each wire in the set is pre-cut to exact length so the wire sets are ready to install right out of the box.

All-Silicone Wires

The 7 and 8mm ignition wires are SAE J2031 Class E rated, the highest quality wire used in the industry. These wires can withstand temperatures from -40° to 428° F and pass tests covering everything from electrical properties to shrinkage to chemical resistance and accelerated life testing.
