Constant high-temperature cycles inside the heavy-duty engine bay break down internal coil epoxy windings and weaken primary\/secondary winding insulation. Over time, this leads to micro-arcing, intermittent secondary ignition breakdown, and burned electrodes on high-mileage plugs. As internal resistance climbs, the factory ECM records erratic misfires, sluggish throttle response, elevated exhaust gas temperatures, and decreased fuel economy under payload.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit replaces deteriorating components with 8 high-dielectric replacement ignition coils engineered to interchange with \u003cstrong\u003eUF413\u003c\/strong\u003e and \u003cstrong\u003e12611424\u003c\/strong\u003e specifications, paired with 8 fine-wire \u003cstrong\u003eNGK 3186\u003c\/strong\u003e platinum spark plugs.
