Toyota Vellfire Spark Plug Replacement — When & Cost Malaysia
Vellfire 2AR-FE uses 4 iridium plugs (DENSO SK16HR11), change every 60,000–80,000 km. Worn plugs on a heavy MPV cause noticeable sluggishness and fuel consumption increase.
Vellfire Spark Plug Guide
Vellfire H30 (2AR-FE, 2.5L) uses 6 iridium spark plugs — DENSO SK16HR11 or NGK ILKAR7L11. The H40 (T24A-FTS, 2.4T) also uses 4 iridium plugs — DENSO SK20HR11 or NGK ILKAR7L11. Both are iridium long-life plugs rated for 100,000 km — but in Malaysian conditions (short trips, city traffic, high humidity) we recommend replacement at 60,000–80,000 km for optimal performance. Worn plugs on a hybrid cause misfires that stress the hybrid motor-generator.
Replacement Cost (Bandar Sri Damansara Workshop)
- H30 (6 plugs, 2AR-FE): RM 400–600 parts + labour
- H40 (4 plugs, T24A-FTS): RM 280–420 parts + labour
- Never use copper or platinum plugs — iridium only for these engines
