Each kit contains two 30-inch wires with a 7mm diameter core and a molded rubber boot on one end to protect the connection to the plug. Built from high-performance insulation and a conductive fiber core, the assembly aims to maintain consistent ignition performance and increase wiring flexibility to reduce strain during routing.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these wires replace original Johnson outboard leads?\u003c\/h3\u003e\n\u003cp\u003eThe HQPARRTS 0310000 wires match the common dimensions and connection style used on many Johnson outboard engines, so they install in the same routing as the factory harness. The molded plug boot and specified length let you connect without altering mount points, while the fiber core transfers the spark with minimal loss when properly seated.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo 30\" wires per kit for dual-cylinder routing or spare use\u003c\/li\u003e\n  \u003cli\u003e7mm diameter conductor compatible with standard outboard plug gaps\u003c\/li\u003e\n  \u003cli\u003eMolded rubber boot on one end for secure plug sealing\u003c\/li\u003e\n  \u003cli\u003eDesigned to align with OEM connection styles for Johnson engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat should I know about installation and preparation?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward but requires a small prep step: trim the wiring harness port to allow the wire to seat fully, and ensure the fiber core is properly connected when inserting terminals. Measure routing before final installation to avoid twisting or over-stretching the leads; their 30-inch length increases flexibility but still benefits from correct placement.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTrim harness ports slightly so wires insert flush\u003c\/li\u003e\n  \u003cli\u003eConfirm fiber core is fully connected to the terminal for reliable spark transfer\u003c\/li\u003e\n  \u003cli\u003eRoute to avoid excessive bending or heat sources that degrade insulation\u003c\/li\u003e\n  \u003cli\u003eUse dielectric grease at boots if desired to improve moisture resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and build quality can I expect?\u003c\/h3\u003e\n\u003cp\u003eThese ignition leads use high-performance insulating material around a fiber-conductive core to balance durability and electrical performance.
