BLUE STREAK 8mm Spark Plug Wire Set - Softail MC-SPW5

Reliable spark plug wire performance is fundamental to engine ignition—any degradation in wire quality directly impacts combustion efficiency and throttle response. The BLUE STREAK 8mm Spark Plug Wire Set is engineered with triple silicone construction to withstand extreme under-hood temperatures while maintaining consistent electrical conductivity across your Softail's firing cycle. This is the difference between a bike that runs crisp and one that develops hesitation and misfires.

Built to SAE CLASS E J2031 specifications, these wires handle sustained heat exposure that would degrade inferior competitors, ensuring reliable starts and stable idle whether you're cruising or pushing hard through the RPM range.
