Spark plugs

[Notracks5150]

I hope to revive a thread I stumbled across and subsequently from 2005 ish regarding Spark Plugs for 2UZ-FE (98 LX470 USA in my case)
It contained a lot of information comparing different Manufacturers, different iridium tip sizes, and gaps.
However searching for "Spark plugs" yields no results.
If anyone has information about plugs maybe we can get more current data in one spot

What is it you are trying to do? trying to get better gas mileage, longer life, more HP... most on here just likely go with OEM and get done with it.. so maybe you can start explaining and hopefully someone will chime in.

Just go OEM and call it a day.

When I got my 100 at 60k miles in 2019, I bought the NGK 4589 Laser Iridium spark plugs because of longevity.
They are rated for 100k miles.
Today, I only put 23k miles so far.

OEM part number 9008091180 for my 2005. Might want new gaskets too, 11193-50010.


Cheers

Actually the denso kit 671-8184 is a much better value than OEM gaskets. Just installed the kit last night.

OEM Denso SK20R11 is what you need.

Pre gapped according to direct question to Denzo SK20R11 is .044
All 8 are clearly at .040
I have guestioned Denzo and haven't received clarification.
I'm just trying to sort out conflicting information.
And gain some in the process
