These are high quality 8mm ignition wires made specifically for magneto applications. The wires are constructed from a stainless steel alloy to deliver maximum spark at the plug with the least amount of resistance possible. They also have a two layer silicone construction for heat resistance and feature ninety degree boots molded to the wires on one end. Wire set also includes straight terminals and boots, so that the wires can be cut to the desired length before installation.
