Spark plug Champion or Denso

Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.

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.

I have measured resistance above 5k and determined the plug to be causing a problem. Typical resistance is 1-3 kOhm, sometimes less for a new one.

Yes! I had a set of iridium spark plugs bought off Amazon that were counterfeit! They were denso but I didn’t discover it till about 40k miles later when I had a misfire. Pulled plugs and they were toast… first set lasted 120k and looked fine..

I tried Denso once and didn't have great luck with them.
