Built with a ferro-spiral core for stable resistance and ceramic boots rated for extreme temperatures, the kit addresses the typical failure points of aging ignition systems while maintaining correct length and fit for the listed engine families. Use the included sizing guidance to confirm fitment before purchasing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this wire set improve ignition reliability?\u003c\/h3\u003e\n\u003cp\u003eThe wires rebuild the connection between the coil pack and spark plugs, minimizing misfires caused by cracked insulation or corroded terminals. The ferro-spiral core provides consistent resistance per foot so spark energy reaches the plug without excessive leakage.
