Over time, internal winding insulation cracks, primary resistance increases, and silicone boots harden. This dielectric degradation leads to micro-arcing and secondary spark blow-out, resulting in P0300-P0304 cylinder misfires, unburned hydrocarbon buildup, rough idle, and significant loss of low-end torque during towing or steep trail ascents.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition package features two high-dielectric epoxy-potted coils engineered to match factory dwell times and step-up ratios without straining the factory igniter circuit. Paired with \u003cstrong\u003eDenso Platinum (4503)\u003c\/strong\u003e spark plugs, the fine-wire center electrode lowers the required breakdown voltage and resists erosion under high cylinder pressures.
