凯迪拉克蓝旗亚阿尔法罗密欧 点火线圈 55214926 0221504026 全新选择

If your Jaguar/Alfa Romeo/Chrysler vehicle experiences acceleration weakness, idle jitter, engine warning light, or even cold-start difficulty, it typically indicates ignition coil aging or insulation breakdown, resulting in insufficient ignition energy or misfire. This coil converts low voltage to high voltage to provide stable ignition energy to the spark plugs, ensuring smooth engine operation and fuel combustion. OEM numbers 55214926 and 0221504026; compatible with multiple four-cylinder engines in these brands. During installation, ensure coil and spark plug contact securely, and check that the connector is firmly seated to avoid secondary faults from poor connection.
