Mercedes-Benz GLA Spark Plug Replacement Malaysia
GLA M270, M260 and M264 engines all use long-life iridium/platinum plugs at 60,000 km. Worn plugs in Malaysia's climate cause slightly rougher idle and increased fuel consumption.
Iridium plugs, 4-cylinder engines (M270, M260, M264). Replace every 40,000 km in Malaysian urban driving. Worn plugs cause rough idle, hesitation and occasional misfire codes. Cost: RM 250–350 supply and fit.
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 RM 350–550 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.
