It comes with a 500 ohm per foot resistor, providing greater spark energy to improve fuel burning efficiency for better mileage, more power, and a smoother idle.
The inner cable is a combination of a helically wound aramid fiber conductive core to enhance strength and durability.
The boots come with vibration-proof double-lock connections for maximum reliability.
RFI (radio frequency) signals ensure that the bike's electronic components function perfectly.
Black silicone boots with double-spring closure match the cable color and help protect against high temperatures.
