original spark plugs in 2021 4R

[08 Hilux Surf]

I have a 2021 4R Premium TRD Off Road. Please let me know if this year/trim originally came with Denso copper spark plugs or a iridium plugs? I'm at the mileage of 38K and wanted to know if it's time to replace or still good to for another 45-50K. Thank you.

I have a 2020, same trim, and still have the original plugs and I'm at 71,880. Your good to go and beyond. Plugs last a long time.

Thank you for your reply/advice. Do you know if they're Denso copper plugs or iridium?
I had a 4th generation in the past, and the manual indicates the same Denso(NGK) copper plugs K20HR-U11 as the 4th gen.

My 2023 ORP's owners manual says -I assume the 21 ias the same:

I don't know what plugs I have, I'll have to look in the user's manual. I'll get back to you. Probably the same as above.

i have this saved , think the manual is 10 years or 120k miles to change them out

my 2016 TE has about 90K and still runs smooth as butter. No need. I have no ideal what plugs are in it.

My plugs are the same as FoxtrotRomeo shows.

Absolutely no need to replace them now. These plugs go their advertised lifespan and then some.

Thank you guys! I looked at the wrong (4th gen) manual, my 5th gen manual shows the same as FoxtrotRomeo, sorry for the confusion. Looks to be iridium plugs, so no need to change for a while like you all commented. Thanks again guys!

My ‘19 Limited has SK16 iridiums(just changed them at 98K, truck was still running great!).
