The most advanced, most trouble-free wire you can buy. Outlasts conventional spark plug wires 2-to-1. Standard Plus wire has a core aramid (a super-strong, heat-resistant Kevlar), sheathed with a thick layer of conductive silicone rubber, which provides unsurpassed toughness and heat resistance. The superior thermal resistance of silicone insures against core burn-out and the extra thickness of the silicone sheath makes a more reliable electrical connection between the core and the crimped plug terminal.
