High-tension plug wires help provide a stronger spark for improved combustion. An extremely low resistance core provides the high conductivity needed to carry a strong current to the spark plugs. The current is then shielded from the magnetic electrical interference by the hyper silicone and metal mesh cable. Grounding each plug wire minimizes electrical noise. Furthermore, the cable material is highly heat resistant and gasoline proof, increasing the wires'life under abusive racing conditions.
