Spark plug replacement.
When does Lexus recommend spark plug replacement?
Has anyone changed their's already? Lexus part # 90919-01249 is the part number but it looks like Denso FK20HBR11 is the same thing for less money.... but are the OEM Lexus ones pregapped? If they are, what are they gapped at?

Iridium plugs are rated for 192,000kms or 12 years...whichever comes first.
Personally I wouldn't wait that long...6 years would be a good compromise.
3 are easy to change...the other 3 need a little more work...but within the realm of possible for the DIY with some basic hand tools.
