Over time, prolonged heat soak degrades the factory coil epoxy insulation, causing internal winding shorts and micro-arcing. Paired with aged spark plugs suffering from electrode erosion and widened gaps, this degradation causes severe misfires under load, increased hydrocarbon emissions, carbon tracking, and an unrefined, rough idle characteristic of failing \u003cstrong\u003eE-Body\u003c\/strong\u003e and \u003cstrong\u003eK-Body\u003c\/strong\u003e ignition modules.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit resolves voltage drop and spark leakage by pairing four heavy-duty waste-spark ignition coils with eight factory-grade \u003cstrong\u003eACDelco\u003c\/strong\u003e spark plugs. The coils are engineered with high-dielectric epoxy potting and precision-wound copper secondary windings to resist thermal cycling and prevent arc-through.
