OEM Denso is what I used from the dealer. Whatever they put in them. I know they come from the factory with NGK on one side and Denso on the other. These were at least all Denso so they had been replaced at least once.
I think my Tundra has the Iridium plugs.

I'm not having much luck with those, I think the problem is the iridium is only on the tip and not the ground. My ground strap wears very quickly due to the 5vzfe having waste-spark ignition system. More on that: https://www.yotatech.com/forums/f2/e...h-bank-177019/

I'm an old-fashioned wrench. I LIKE looking at my spark plugs every 30K. There is no better snapshot into the internal health of your engine (at least, up there with DTC codes and UOA's). If I spent more money on longer lasting plugs, I'd still want to pull, clean and regap them. Easier just to buy cheap new ones. OEM NGK's from NAPA for me--NAPA is two miles away, stealer is 15.

Do NOT re-gap platinum or iridium plugs, can make the tip break off in the motor, that is bad news.
The gap will open up a lot over time, just get new plugs to replace them.

Right now i think i just have some BKR6E's in there, i needed new plugs and didn't have time to order in the IK22's.
Gonna swap them out for them next oil change most likely as i am sure these plugs will be done by then.
Didn't notice any real difference going from these to the dual plugs i pulled out (pretty sure they were the IK22's).

What are you not happy about? Mine seemed to work ok.
Although i think i also used an NGK iridium dual electrode plug at one point, can't remember which ones i used for a long time before i swapped to the coppers.

They wear out too fast (the ground straps). The center tip is long wearing (IR) but the ground strap is nothing special and the waste-spark ignition system uses a negative (-) to positive (+) spark on one plug and the other side fires with opposite polarity which wears the ground strap badly.
I'm looking at the NGK laser platinum (they have dual platinum surfaces) if I can find them in 2 steps cooler heat range for the forced induction.

Oh, if thats your only complaint i had that same "problem" with all the plugs i have tried (3 or 4 now). That doesn't bother me, that is just how it is going to be with our ignition systems. I don't mind changing plugs every few oil changes.
I mainly was looking for different plugs that would give me more performance but no clear winners on that front so far.
