Audi A4 Ignition Coil – Complete Guide, Technical Specs, and Replacement in Nairobi

The ignition coil is one of the most vital components in the Audi A4 engine system, responsible for converting low-voltage power from the battery into the high-voltage spark required to ignite the air-fuel mixture inside the cylinders. A faulty ignition coil can cause misfires, poor fuel economy, loss of power, and difficulty starting the engine. At Natial Drive Nairobi, we supply genuine Audi A4 ignition coils (2004–2019) to ensure your engine performs at its best, with OEM reliability and long service life.

Function of the Audi A4 Ignition Coil

The ignition coil acts as a transformer, stepping up the 12V current from the car battery to as high as 20,000–40,000 volts. This voltage is delivered to the spark plugs, creating the spark that ignites the compressed fuel-air mixture.

A properly functioning ignition coil ensures:

• Smooth engine performance without misfires

• Consistent fuel efficiency

• Lower emissions meeting environmental standards

• Reliable cold starts in any weather
