Is my Spark plug still good?
 

Hello everyone,
New to this forum and just recently got into working on my own car (2014 Honda Civic Ex 1.8L). I decided to check my spark plugs as I bought this car used and it has 125k km’s and they are original. They still look good other than some black grime on them. Still new at this so was wondering if any of you guys have any knowledge o tips on this. I’ve included a picture of one to show what they look like. Consistent with all four.

Thanks!
