What is the role of Mitsubishi Galant 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 Mitsubishi Galant 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 Mitsubishi Galant 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 Mitsubishi Galant 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.
