Here is a thread with normal EFI system plugs.

So many variables to a clean burn with EFI. If it runs good let it go, and go and go.

Thanks everyone to share the advice/wisdom.  If it runs, let it runs like an energizer bunny.  On and on.

 

let's see any other issue popup.

 

regards

I’m in Southern California.  I can understand there are metal that can withstand certain temperature, but whether you drive in snow or Sahara, the engine still hot the same nevertheless.  Well at least inside the combustion chamber.  I don’t know what I am talking about, obviously ?

If you are trying to compare your Z plugs to a modern cars plugs, dont. Modern car ignitions are much, much stronger and need to be respected.  They can put you on the ground. The hotter ignition helps the plugs stay cleaner and they tend to be whiter
