Over decades of operation, extreme thermal cycling degrades the factory epoxy potting and hardens the silicone spark plug boots. This leads to dielectric breakdown, high-voltage micro-arcing against the cylinder head casing, and intermittent misfires under load. Concurrently, aged nickel or standard copper electrodes erode, expanding the plug gap and placing excessive electrical strain on the primary ignition drivers, resulting in hesitation, unburned fuel wash, and loss of low-end torque.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit resolves thermal breakdown by utilizing reinforced thermoplastic coil bodies filled with high-dielectric epoxy resin to prevent internal arc-over. Heavy-gauge primary and secondary copper windings deliver consistent spark energy across high-RPM load cycles. Paired with fine-wire iridium spark plugs, the system reduces the required ionization breakdown voltage, resists carbon fouling, and delivers a stable, focused flame kernel.
