Delphi Technologies 12138616153 Direct Ignition Coils

Description:

The Direct Ignition Coils are used in electronic ignition systems to convert low-voltage electrical power into high-voltage energy required to ignite the air-fuel mixture inside the engine cylinders. Commonly installed in modern gasoline engines equipped with coil-on-plug systems where each cylinder has an individual ignition coil mounted directly on the spark plug. Automotive technicians use these ignition coils for misfire repair, ignition system maintenance, engine performance restoration, and replacement of failed or weak coils causing rough idle, poor fuel economy, or engine warning lights.

Applications:

The Direct Ignition Coils are commonly used in a wide range of gasoline vehicles equipped with coil-on-plug ignition systems including BMW, Mercedes-Benz, Audi, Volkswagen, Ford, GM, Toyota, Honda, and Nissan platforms depending on engine configuration. They are suitable for ignition system repair, routine maintenance, engine tuning, and replacement of worn ignition components to restore proper combustion, improve throttle response, and maintain emissions compliance.
