Ignition system – coils, spark plugs and control components

In petrol engines, the ignition system creates a spark at the correct moment. Its components must match the engine and engine control unit. This category includes ignition coils and related service products. Glow plugs are also available, but they assist diesel engine starting and are not part of spark ignition.

What does engine misfiring mean?

Rough running, jerking, loss of power and an engine warning light may result from a faulty coil, spark plug or electrical wiring. Fuel, compression or engine management issues can cause similar symptoms. Before buying parts, examine fault codes and live data and confirm the diagnosis.

How to select ignition components

First identify the engine code and compare the OE number. For ignition coils, check connectors, pin count and design; for spark plugs, also verify specifications, dimensions and installation torque. Different systems may be used within one vehicle generation.

What precautions matter during servicing?

Ignition components operate at high voltage, so do not touch them while the engine runs. Use parts compatible with vehicle documentation and follow installation procedures. See ignition coils, spark plugs and glow plugs.
