菲亚特系列点火线圈 46446039 启动顺畅稳定点火

This replacement matches OEM standards in material and process, using high-density epoxy encapsulation and copper core windings; superior heat resistance and vibration resistance to some low-cost aftermarket parts; service life closer to OEM. OEM number 46446039, also compatible with 46472440 and 46480361; fits many Fiat series engines with single-cylinder ignition systems, including Punto and Doblo. Function provides stable ignition voltage to ensure smooth cold start and steady idle, reducing misfire risk. Replacement difficulty moderate; remove old coil and ensure plug connection secure; torque bolts with a torque wrench to avoid over-tightening.
