No one has this information?? Using the search function is only bringing me to the first and second generation oil changes.

3GS OEM Iridium spark plugs does NOT require changing until 100k mark.

Quite rare for anyone replacing them early on.

I've seen opinions stating that although the plugs in the GS350 and other cars don't need changing for 100k miles, it's recommended they be removed and reinstalled before that (60k?) because they can be 'frozen', and damage may occur when attempting removal at 100k. Thoughts?
