Nology Hot Wires store coil energy until it can be released as an ultra-short, ultra-hot spark. Expect better horsepower and torque (2% to 5%), no fouled plugs, less backfires and a better starting engine. Each kit includes a 30” Hot Wire with grounding strap, 90 degree or straight spark plug cap, in-line wire connector and heat shrink tubing. Order one kit per cylinder.
