Over time, internal potting epoxy degrades, triggering secondary winding resistance drift and dielectric casing breakdown. This insulation failure leads to micro-arcing and intermittent spark discharge under load. Compounded by widened spark plug gaps from electrode erosion, the weakened ignition energy results in OBD-II misfire codes (P0300–P0306), unburnt fuel dumping into catalytic converters, and sluggish off-idle throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition tune-up kit delivers direct-fit coil-on-plug units built with thermal-resistant thermoplastic housings, copper windings, and high-dielectric epoxy to prevent voltage leakage under high-load operating conditions.
