上海汇众100点火线圈A1611583103，原厂品质直接替换安装

When Shanghai Huizhong 100 experiences starting difficulties, weak acceleration, idle jitter, or engine warning light, the original ignition coil may no longer supply sufficient high voltage due to long-term high-temperature exposure or aging. This coil converts low voltage to high voltage to precisely ignite the air-fuel mixture in cylinders, ensuring smooth operation and power output. Compatible with Shanghai Huizhong 100 (4-cylinder); OEM A1611583103. Replacement directly replaces original part. Before installation, disconnect battery negative and ensure coil-to-spark plug connections are snug to avoid miscontact.
