阿尔法罗密欧Giulietta 1.4T 点火线圈 55229959 0221504036 高性能点火

Your Alfa Romeo Giulietta 1.4T experiences acceleration stumbles, rough idle, or check engine light on, usually indicating ignition coil aging or insulation degradation leading to insufficient spark energy. The ignition coil converts low voltage to high voltage to ignite the air-fuel mixture, ensuring smooth engine operation and ample power. This product OEM number is 55229959 (corresponding to 0221504036), for Alfa Romeo Giulietta 1.4T four-cylinder engines. Installation must use a torque wrench to tighten bolts to standard torque and ensure high-voltage ignition coil connectors are fully locked to avoid poor contact and secondary faults.
