三菱/哈飞/福田/比亚迪通用点火线圈MD361710 MD362903 099700-048

General replacement parts for Mitsubishi, Haifei, Futian, BYD two-cylinder engines; OEM numbers include MD361710, MD362903 and 099700-048. The ignition coil mounts atop the cylinder head and connects directly to the spark plug, converting low voltage to high voltage to ignite the mixture. Replacement difficulty is medium; approx. 0.5–1 hour; pay attention to the firing order of high-voltage leads. If acceleration is weak, idle shakes, or starting is difficult, coil aging or breakdown is indicated and replacement is required.
