2019 4 gen - dealer sparkplugs were part number ZC20HPR11 > Denso spark plug.
I’m from EU, Scandinavia and that part number were on my original ones I pulled out.
Plugs(Denso IK22) coils(DENSO or Hitachi) and a valve adjustment, all due at 100k. They really do make them run better and much more reliably.
I installed Denso a few weeks ago.
Densos. Buy them off rock auto.
The Denso IHKs are my go to for the last 10k on their tune.
Either one, but I found the Denso to be cheaper and easier to get. No issues with them.
You can usually find DENSO IRIDIUM Spark Plugs , which are the OEM Supplier, for about $15 each at any Advance Auto or other major auto parts store.
Yesss got denso coils and spark plugs off their site and they have been great
And, before you get too far, are you replacing with the right plugs? I presume it’s the 2AZ 4-cyl since you’re not asking us how to get to the back plugs. The right ones are the Denso Iridium Long Life or the NGK Laser Iridium.
Bought some Denso 3450 Irdium plugs online. After reading about counterfits. I decided to test mine.
All are gapped .43 for the OEM spec for a 2014 Nissan Xterra. I measured the Irdium electrode tip which is 0.7mm and appears blue
