Factory coil packs located directly above the cylinder head endure continuous heat soak cycles, leading to degraded internal copper windings, micro-fracturing in the dielectric potting, and breakdown of the silicone spark plug boots. Over time, this degradation increases secondary resistance, resulting in spark blowout under boost, hesitation, fuel trim drift, and DME misfire fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit pairs six direct-fit coil-on-plug ignition coils with six precision \u003cstrong\u003eBosch Platinum\u003c\/strong\u003e spark plugs to establish factory-spec arc stability.
