双龙柯兰多点火线圈 1721580003 A1721580103 原厂替代

Does your Sion Koraldo (Shaan) experience acceleration stalls, idle jitter, starting difficulties, or engine fault lights? These symptoms typically indicate ignition coil aging, causing insufficient ignition energy or intermittent misfires. When functioning properly, the ignition coil converts battery low voltage to high voltage to ignite the air-fuel mixture, ensuring smooth operation and power. OEM number A1721580103 (factory substitute) fits DaLung Khaz Lando 4-cylinder engines. Installation note: work only with a cold engine; ensure clean, oil-free contact surfaces between coil and spark plug; tighten strictly to maintenance manual torque to avoid damage.
