Spark plug Denso or BERU

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

For what it's worth, I've changed my plugs twice (OEM to Denso to Beru-RS7) and never noticed any oil or any difference in color between the plugs.

the densos work fine, the point of swapping is not for any performance gain, rather to prevent shattered ceramic from raining into your cylinders
