Toyota Corolla Altis Spark Plug Replacement Malaysia
E140 uses copper plugs (40,000 km); ZRE182 uses iridium plugs (80,000 km). The difference in cost and lifespan explained.
All Altis generations use NGK or Denso iridium plugs — replace every 80,000 km. The 2ZR-FE/2ZR-FBE engines are port-injected, so carbon fouling on plugs is less severe than direct-injection engines.
Spark Plug Replacement
- NGK iridium or Denso iridium (set of 4): RM 180–300
- Labour: RM 60–100 — good access on all Altis generations
