I know that I am re-visiting this but I thought I would put it out there for clarification.

I am at the 96000KM(60000MI) service interval and the maintenance manual says to replace my sparkplugs.

Reading through the forums everybody is saying that they are good until 145000KM(90000MI).

The only other difference that I can see is maybe a Canadian or US version IS300?

Can anyone clarifiy what kind of plugs I have and when they should be replaced?

Thanks everyone!

BTW: I have a 2001 IS300

I think I am running on original plugs on my car. I have over 110,000 miles. I do need to change them, but I am not losing any power.

US motors and Canadian motors are identical. Unless you have a beams motor
