Volkswagen Passat CC/Sharan (1.8T/2.0T) and other EA888 engine vehicles fitted with ignition coil 022905100G. This product uses German process standards; core parts employ high-purity copper core coils and high-temperature epoxy encapsulation; heat dissipation and aging resistance are stable, measured lifespan up to 80,000-100,000 km. Functionally, it converts low voltage to high-voltage pulses to precisely drive spark plugs for ignition. Replacement difficulty is moderate; requires removing the engine undertray and ignition coil connector; after replacement, idle stability and acceleration response are restored.
