Continuous thermal cycling breaks down internal copper windings, degrades epoxy insulation, and creates micro-fractures in the housing. Over time, high electrical resistance causes secondary coil output drops, leading to incomplete combustion, rough idle, hesitant throttle tip-in, and spark blowout under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet or exceed OEM specifications, these direct-fit ignition coils feature reinforced thermoplastic housings and high-dielectric epoxy potting to eliminate secondary winding arcing and withstand underhood heat soak. Paired with fine-wire iridium spark plugs, this kit provides a consistently focused electrical arc requiring lower initiation voltage. The corrosion-resistant iridium center electrodes prevent premature gap erosion, maintaining a sharp spark boundary across the powerband.
