Over time, OEM coil housings suffer thermal fatigue, leading to internal dielectric breakdown, micro-arcing, and epoxy potting fractures. Coupled with electrode gap erosion on 16 factory plugs, this causes high-load spark blowout, hesitation during Multi-Displacement System (MDS) cylinder deactivation transitions, and erratic \u003cstrong\u003eP0300–P0308\u003c\/strong\u003e misfire codes under heavy towing loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis master overhaul kit features 8 reinforced coil-on-plug assemblies engineered with high-conductivity copper windings and high-grade silicone boots to suppress flashover and resist heat soak.
