东南/凯越JU 03-05款 3针接口点火线圈 19005236 原装位安装

For Southeast Asia Dongnan or Kaiyue JU 03–05 models, rough idle, weak acceleration, engine vibration, or fault light often due to ignition coil aging or internal short. The coil converts low voltage to high voltage to provide precise ignition energy for the spark plugs. OEM number 19005236; fits Southeast/Ningbo JU 03–05 4-cylinder engines; 3-pin OEM plug design requires no modification. Disconnect battery negative before installation; ensure coil–spark plug connections are tight to prevent high-voltage leakage or poor contact.
