Mercedes-Benz G-Class Spark Plugs Malaysia
Mercedes-Benz G-Class spark plug type, replacement interval and Malaysia pricing — iridium plugs.
G-Class Spark Plugs — M177 V8 (8 plugs)
- 8 iridium spark plugs — replace every 60,000 km
- V8 layout means more labour time — Malaysia cost all 8 plugs + labour
Spark Plugs — Mercedes Petrol Engines Malaysia
Mercedes-Benz petrol engines use NGK or Bosch iridium spark plugs — change every 60,000 km. On turbocharged M270/M274 engines (C200/C180/GLC200), misfires under boost degrade the catalytic converter and can damage the turbo — do not delay plug replacement. Budget for a set of 4 iridium plugs including labour. Bosch OE plugs are the factory specification — aftermarket premium plugs (NGK Laser Iridium) are an acceptable alternative. Never use copper plugs on modern Mercedes turbo engines.
