Over time, thermal fatigue causes dielectric degradation in factory coil windings and internal primary boots, prompting high-voltage micro-arcing and intermittent secondary-ignition dropouts under elevated manifold pressures. Additionally, standard spark plugs suffer ground strap erosion and carbon tracking, precipitating cold-start stutter, power hesitation under load, and catalyst-damaging unburnt hydrocarbons.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit integrates four pencil ignition coils and four fine-wire iridium spark plugs precision-engineered to meet demanding forced-induction operating parameters. The replacement coil bodies utilize high-temperature epoxy encapsulation and reinforced vulcanized silicone boots to resist flashover, oil degradation, and thermal puncture. Paired with laser-welded iridium electrode spark plugs designed for high melt points and minimal gap growth, this direct-fit system maintains stable flame propagation across the entire powerband.
