Over extended drive cycles, severe thermal cycling hardens the factory silicone boots, leading to dielectric breakdown and micro-arcing against the spark plug tube walls. Simultaneously, primary and secondary coil windings suffer resistance drift from thermal stress, starving the combustion chamber of full ionization voltage. Combined with eroded electrode gaps on aged factory plugs, this breakdown manifests as hesitation under load, erratic idle, reduced fuel efficiency, and random cylinder misfire codes (P0300–P0306).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul kit pairs six high-dielectric pencil coils with fine-wire iridium spark plugs to re-establish optimal flame kernel propagation. Each coil features premium copper winding with reinforced internal epoxy potting to resist thermal degradation and internal shorting. High-tear-strength silicone boots provide high voltage insulation against flashover. The matched iridium-tipped spark plugs feature ultra-fine center electrodes requiring lower striking voltage while resisting spark erosion under sustained high-RPM operation.
