There are some hex heads and torx heads securing the plenum to the engine. I am at 62k miles on my 16, but plan on swapping out the plugs around 100k. During that time, I'm going to subscribe for the two day Toyota TIS (technical information system) service manuals and download all the PDFs I may need for long term maintenance for the car.
From the maintenance schedule:
FACTORY RECOMMENDED SERVICE FOR 60K MILES /72MONTHS
- Check Installation Of Driver's Floor Mat
- Reset Maintenance Reminder Light
- Reset Oil Maintenance Reminder, if Oil was Changed

Just FYI, my Lexus dealer advised me spark plugs had to be replaced at the 60k mile service in order to meet the emissions warranty requirement. Luckily I had a free 60k service since my vehicle is CPO. That said, I didn't replace the ones in my 2010 4runner until it hit 120k miles and it was fine. I'm sure this would be fine too but I didn't have to pay for the service so it was done.

Is this the Lexus maintenance schedule specific for 2016+ RX?
In Canada Iridium spark plugs are due at 192,000km or 120,000 miles

Don't know, but logic would seem to dictate that if they're working correctly at 100K or 110K miles, the car should pass the emissions test and no one should care about the age of the plugs. Are there states that legislate spark plug change intervals?

The only thing I can personally think of is if you do have an issue with your emissions system (for whatever reason) and Lexus determines you didn't do the plug change at 60k miles, your warranty on those systems may be void.

Here in USA, my 2021 manual says 60,000 miles for spark plug change. I will call my local Toyota dealer as well as the Lexus dealer to compare prices. As long as it is maintenance and not warranty work. The information will also be entered into the Lexus/Toyota database just the same. The parts will be identical. Toyota techs know how to work on this engine. Unless you want the ambience of the Lexus waiting room.

The Toyota dealer can certainly perform the work, but cannot enter anything on a Lexus ledger, history or whatever, that's reserved only for Lexus dealers, that's how Lexus protects its dealer's interest.

In USA, Toyota dealers can enter their maintenance records. Last time, I had my RX serviced at Toyota dealer, within a week, the record appeared on my Lexus Driver Service History.

BTW, drivers can make manual entries in the drivers.lexus.com service history, too, for items performed DIY or by a 3rd party. Since the dealer and driver maintenance systems are possibly (likely?) different, those manual items may not be visible to dealership service departments.

Well if the Toyota and Lexus are the same dealers, I do not think that the Toyota side will take your car for service. Within 20 miles radius of my town, there are two Toyota dealers, the one shares with the same Lexus dealer refused to take my car for service and asked me to schedule service with their Lexus shop. I have to visit the other Toyota dealer for service.

It may make you feel better, but any buyer/dealer will not use that source of info.
