Over time, high combustion pressures generated by the Eaton M62 roots-type blower accelerate dielectric breakdown of the factory silicone boots and internal coil potting. Combined with electrode erosion on aging spark plugs, the widened gap demands higher firing voltages than fatigued factory windings can sustain, leading to high-RPM spark blowout, rough cold starts, and persistent P0300 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit restores high-energy ignition transfer with direct-fit coil-on-plug units engineered to meet or exceed \u003cstrong\u003e12584368\u003c\/strong\u003e OEM parameters. Premium copper core windings and heavy-duty dielectric insulating boots isolate secondary voltage to prevent arc-over under boost.
