Ton's Performance wires are built with a spiral wound alloy conductor with a high dielectric insulator, fiberglass braid, followed by two layers of silicone resulting in 10mm thick silicone jacket to protect against heat and tears. Ton's is one of very few companies that offers custom wires for many different applications in the aftermarket motorsports world.
