Spark plug Autolite or Denso

I am running platinum Autolite plugs in my 2.3 rwd and don't regret it

Have some I'm waiting to try out in my turbo 4age after using bkr7e ngks for years. I mean denso is an A1 company and they offer heat ranges colder than NGK so probably worthwhile for my turbo engine.

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.

In my 206 classes we run this autolite sparkplug because it’s required.

My understanding is that we switched because people were buying plugs in bulk and looking for ones with the lowest internal resistance believing it would effectively advance the engines timing. Supposedly these autolite plugs are much more consistent.

I bought some Autolite double platinum spark plugs because they were on sale at the Napa where I live but everybody I have tried asking to help me do my spark plugs has gawked as soon as I say "Autolite" and tells me that I'll have nothing but issues with those plugs and that "they're only good for Fords" basically.

Auto lights are trash, Bosch too. I can’t tell you how many times I get a misfire diag that the customer already put plugs in, only to find the garbage auto lights are the issue. A set of oem plugs always fixes it

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 replaced the original ac Delco spark plugs (shown in picture, THEY LOOK BAD) and put with new auto light ones and changed the wire as well. However, after doing so, my truck has been running really rough, almost like it's cammed and misfiring, when its rolling in drive it like to have a little shake.
