Over years of thermal cycling, the original OEM ignition coils suffer from degraded epoxy potting, leading to micro-cracking and internal secondary winding shorts. This heat-induced breakdown causes weak spark generation, especially under load or during towing. Furthermore, the carbon-core spark plug wires break down internally from continuous high-voltage transfer and engine bay heat soak, resulting in increased electrical resistance, poor throttle response, rough idling, and inevitable P0300 series misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition overhaul restores peak electrical efficiency by utilizing modernized materials.

The kit also integrates low-resistance, high-temperature silicone spark plug wires that guarantee maximum energy transfer to the opposite cylinder bank in the waste-spark setup.
