Spark Plugs

How many of you ignore the 40,000 mile spark plug replacement on your LS500?
LS500 owner’s manual says it is necessary to maintain emissions systems warranty.

I did not ignore and I had them save it, trust me not worth it. The spark plugs still looked fairly new and was a waste in my opinion to replace that early maybe 60k makes more sense but even then I think they will still look good.

Yes , I think forty thousand miles is a little bit too soon. Anything out there in writing that gives us clarity as to whether they really need to be changed at forty thousand miles?
Thanks in advance!
Blessings and Best for the day!
