Honda Jazz GK5 Spark Plug Replacement Malaysia
Honda Jazz GK5 uses NGK IZFR6K-11 iridium spark plugs. Replacement interval, installation guide and Malaysia workshop costs.
Jazz GK5 1.5L i-VTEC uses NGK IZFR6K-11 iridium plugs — the same plug as the HR-V RU 1.5L. The port-injection engine keeps the combustion chamber cleaner than direct-injection rivals, so plug life is good.
Replacement interval and cost
Replace every 80,000–100,000 km. Signs of worn plugs: rough idle, hesitation on startup, reduced fuel economy. The GK5's engine bay is compact but plug access is reasonable from above. Cost: RM260–360 for 4 plugs including labour.
