John, my made in japan 2AZ-FE comes with OEM NGK copper v-groove BKR6EYA11. Which model iridium plugs does yours use? Is there any use of plastics in the chain?
G-man, there are 2 formulations of SLX available here, the one Im using is the ACEA A3 formulation, the other is the ACEA A1 formulation, maybe I will try the latter on my next oil change.
