Toyota Avanza Spark Plug Malaysia
Toyota Avanza Spark Plug guide and repair information for Malaysia owners.
Avanza spark plug specs and intervals differ between old and new generations. Using the wrong plug accelerates wear.
3SZ-VE — Iridium or Platinum at 60,000 km
NGK ILKAR7L11 or Denso SC16HR11. Old 3SZ-VE can also use copper plugs changed every 20,000 km if budget is tight. Iridium is preferred — the VVT-i system needs consistent spark to avoid misfires.
2NR-VE — Iridium at 80,000 km
NGK ILKAR7B11 or equivalent. 4 plugs total. Replacement cost at our workshop. Never use copper plugs on 2NR-VE.
