tim's rx300

Sorry! should have said that the plugs are the original equipment which I think are iridium rather than platinum. thanks, Tim.

Hi - At what mileage does Lexus USA recommend for spark plug replacement. Lexus UK recommend 60,000 miles but I was told that Lexus USA recommend 100,000 miles. Is this correct? thanks, Tim.

In the UK, Lexus recommend 60k miles in the service book. Does anyone know what is recommended by Lexus in the US service book?? thanks, Tim.

Hi - this is my first post on this site. Can anyone tell me the US recommended mileage or lifecycle for changing the spark plugs on an RX300 or RX330? thanks, TIm.
