    This 8.5mm Super Conductor wire set is built for incredibly low resistance without electronic interference, using a copper alloy conductor wound around a ferro-spiral center core to produce only 40-50 ohms of resistance in a 12-inch length. The ferromagnetic core creates an effective EMI "choke" that keeps interference inside the wire, and the silicone/synthetic outer sleeve resists heat, abrasion, and tears. This extra-long, universal single wire is supplied with black Hemi tubes, boots, terminals, and a mini-crimper, pre-crimped at the spark plug end so it can be cut to a custom length.

    Specifications:

    • Application: Gen III Hemi
