Shop replacement ignition and preheating components for petrol and diesel vehicles. These systems play an important role in starting the engine and supporting efficient combustion.

Petrol engines commonly use spark plugs and ignition coils, while diesel engines use glow plugs and related preheating components. Some vehicles also use specialised ignition control modules and sensors.

Ignition problems can result in difficult starting, misfires, rough running, poor acceleration or warning lights. Diesel preheating faults may be particularly noticeable during cold starts, although starting problems can have many possible causes.

Correct component selection is essential because spark plugs, glow plugs and ignition coils vary according to engine design, heat range, voltage and manufacturer specification.

Use your vehicle registration number, VIN, make, model, engine and year to identify compatible parts. Engine code and original part number can provide additional confirmation.
