Bougie voor het ontstekingssysteem van de benzinemotor, gemonteerd op de 2.5L viercilinder en 3.5L/3.9L V8 benzinemotoren.

Deze wordt in de cilinderkop geschroefd en levert de ontstekingsvonk die het samengeperste lucht-brandstofmengsel in de verbrandingskamer ontsteekt. Bougies zijn een routineonderdeel en moeten als volledige set op het voorgeschreven interval worden vervangen om een soepele werking en efficiënte verbranding te behouden.

Frequently asked questions

What is the ERR743 spark plug used for?

The ERR743 spark plug delivers the ignition spark on Land Rover petrol engines, fitted to the 2.5L four-cylinder and the 3.5L and 3.9L V8. It screws into the cylinder head and ignites the compressed air and fuel mixture in the combustion chamber. This is the Lucas plug.

How many spark plugs do I need?

The number depends on your engine: the 2.5L four-cylinder petrol takes four spark plugs, and the 3.5L or 3.9L V8 takes eight. Spark plugs are renewed as a full set, so order the quantity to suit your engine rather than replacing them individually.

Which vehicles does this spark plug fit?

This spark plug fits the 2.5L petrol and 3.5/3.9L V8 in the Land Rover Defender, Discovery 1 (1989-1998), and Range Rover Classic. Confirm your engine is petrol and match the plug to your ignition setup, using your VIN if you're unsure of the variant.
