Over continuous heat cycles, the internal copper windings and dielectric epoxy of the factory coils degrade, causing secondary voltage leakages and internal shorts. Paired with eroded electrode gaps on aged plugs, this impedance drop triggers intermittent under-load misfires, rough idle, and unburned fuel delivery that damages expensive downstream catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 12-cylinder overhaul kit features direct-fit coil-on-plug modules built with high-grade magnetic silicone steel laminations and premium thermal-resistant epoxy potting to resist high-temperature breakdown. Matched with precise-gap spark plugs, the package delivers consistent high-kV discharge under peak cylinder pressures.
