What is the role of Ford B-Max spark plugs?

The spark plug generates a spark at the precise moment needed to ignite the air/fuel mixture in the combustion chamber of petrol (or LPG) engines. The engine management system controls ignition timing.

When should you change your Ford B-Max spark plugs?

Manufacturers provide replacement recommendations; refer to your vehicle maintenance booklet. Generally replace every 60,000 km (45,000 km for severe use). Some vehicles with long-life plugs (titanium, platinum, iridium) can go 100,000–150,000 km.

How do I know if I need to change my Ford B-Max spark plugs?

Via the EOBD system (mandatory since 2001 on petrol cars), faulty spark plugs will trigger fault codes, typically P0301–P0304 (misfire, cylinders 1–4). Symptoms include: difficulty starting, misfires, reduced engine power, increased fuel consumption.

Is it difficult to change Ford B-Max spark plugs?

Difficulty level 2/5: technically easy but requires specific tools (spark plug wrench, torque wrench). Key points: wait for cold engine, clean plug well with compressed air before removal, never use a dropped plug, do not grease threads, hand-tighten then torque to specification.
