福特蒙迪欧1.5T/2.0T点火线圈 CM5G12029FB/4S7G12029AA 品质替换

This replacement part meets OEM standards in material and craftsmanship, using high-purity copper core windings and high-temperature epoxy resin encapsulation to resist heat aging and vibration fatigue in the engine bay; tested lifespan comparable to original parts. OEM numbers CM5G12029FB and 4S7G12029AA, for Ford Mondeo 1.5T and 2.0T four-cylinder engines. Functionally, it steps up low voltage to the high-voltage pulses required by the spark plugs to ensure precise ignition timing and full combustion, reducing misfires and jitter. Replacement difficulty is moderate; first disconnect the negative battery, unplug the old coil, and unfasten the mounting bolts; clean oil and dust from the spark plug well to ensure a good seal with the new part.
