Mazda CX-90 Spark Plugs Malaysia — 3.3T Inline-6
CX-90 3.3T: 6 spark plugs (inline-6), iridium, replace every 60,000 km. Turbocharged engine — iridium plugs are mandatory (not copper). Access on inline-6 layout: straightforward from top of engine (all 6 plugs in a row). PHEV hybrid operation: if engine runs mostly short EV-start warm-up cycles, plugs may foul slightly faster — inspect at 40,000 km if frequent short-trip PHEV use.
