Prolonged exposure to high underhood temperatures causes micro-cracking in the primary epoxy potting, allowing high-voltage secondary arc-through to ground. Simultaneously, aging factory plugs suffer electrode erosion and widening gaps. This increases the required breakdown voltage beyond what a heat-soaked coil can provide, leading to cylinder-specific misfires, unburned fuel entering the catalytic converters, sluggish throttle response, and erratic idle stability under sustained load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul kit provides balanced, high-dielectric replacement coils and precision-gapped \u003cstrong\u003eNGK\u003c\/strong\u003e spark plugs engineered to withstand severe thermal cycling. The replacement coil bodies utilize high-temperature thermoplastic housings paired with premium copper wire windings, ensuring rapid saturation and high secondary voltage discharge without dielectric breakdown.
