Toyota Sienta Spark Plug Replacement Malaysia
1NZ-FXE hybrid and 2NZ-FE petrol both use iridium plugs at 80,000 km intervals. Worn plugs reduce fuel economy on these small engines.
Sienta 1NZ-FE (petrol) and 1NZ-FXE (hybrid) both use iridium spark plugs — replace every 80,000 km. Both are port-injected engines, so carbon fouling on plugs is minimal compared to DI engines.
Spark Plug Details
- NGK or Denso iridium plugs (set of 4): RM 150–240
- Labour: RM 60–100 — straightforward on both 1NZ variants
