Toyota Harrier Spark Plug Malaysia
Toyota Harrier Spark Plug guide and repair information for Malaysia owners.
Harrier M20A-FKS (2.0L petrol) and A25A-FXS (2.5L hybrid) both use iridium long-life plugs — Toyota specifies 80,000 km intervals. Both are direct injection engines, so carbon buildup on plugs is more likely than on port-injection engines.
Spark Plug Replacement
- OEM NGK iridium or Denso iridium (set of 4)
- Labour — relatively easy access on M20A-FKS; hybrid A25A-FXS is more involved
