Toyota sounds like great deal if they actually use OEM plug (DENSO iridium). That part alone is \\~$18 each (you need 6).
DENSO , Iridium Long Life, SK20HPR-L11 Spark Plug
I would stick with the specd Denso, leave the coils alone.
I highly recommend avoiding anything other than exactly what is specified in your owners manual, I currently have bad gas mileage because I was too curious to see if the desno two tip would do as good as the other stuff.
I recently was having a misfire in cylinders 2/3, and new plugs and ignition coils cleared it up.
DENSO ZXE24HLR7 is also an excellent OE plug.
Denso 3289 is what I run.
398k on the clock, like 50k on these plugs, she runs clean and smooth.
Denso for my runner
Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that
Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.
