Continuous underhood heat cycling deteriorates internal coil epoxy potting and winding insulation, leading to dielectric breakdown and micro-arcing. Simultaneously, electrode erosion expands the spark plug gap well beyond factory tolerance. This increased gap elevates primary circuit resistance, forcing the ignition coils to work harder until secondary voltage drops, triggering P0300-series diagnostic trouble codes, sluggish throttle response, and unburned fuel dumping into the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition service kit replaces tired hardware with high-dielectric epoxy-molded coils featuring precision-wound copper windings to resist heat soak and voltage leakage.
