Over time, the factory epoxy insulation breaks down, causing secondary voltage leakage, internal winding resistance, and coil housing micro-cracks. Compounding this, worn spark plugs exhibit expanded ground electrode gaps that force coils to discharge at higher operating voltages, triggering unburned fuel delivery, rough idle, catalytic converter damage, and diagnostic trouble codes from \u003cstrong\u003eP0300\u003c\/strong\u003e to \u003cstrong\u003eP0308\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 8-cylinder ignition overhaul kit pairs high-dielectric coil packs with matched platinum-core spark plugs to maintain stable arc discharge under heavy load.
