Default 6th gen spark plug condition



Hello
Is it normal for the spark plugs to have this carbon deposit after 200 miles?
It’s only on the bottom part of the threads.
Regards

Just so you know, the Denso plugs would have been fine. They're used in Toyotas new. Also Denso is a Toyota owned company.

  • Denso plugs, perfectly acceptable.
  • NGK plugs, perfectly acceptable.
  • Bosch plugs, chronic fail.
  • The latest Gee-Whizz-Bang-127-electrode plugs, epic fail.

Just love this thread and the obvious mechanical enthusiasm of the owner.

I want to buy your car when you're done with it!
