Fairly certain that OEM was either Denso or NGK.
I would prefer NGK's over a Denso set.
Will be curious to see what Irontoad ships.
Will save you the suspense. I bought from IRONTOAD.
Plugs they sent are DENSO
Plug wires have toyota over the packaging on the wires itself it says "YAZAKI 2008"
I now have 33,000 or so on my BKR6EIX-11 plugs so just a quick wire swap for me.
Yes yazaki are the wires, plugs are denso. Tried to get the pics for you that says "yazaki" on the wire, but it is written so small, wasn't successful, gave up after 15 pics
