Are you using it in a 230f or a 150f?
It looks OK to me. Its a bit old to read, i.e. too colored.To be serious, you are showing the wrong part. While the overall color gives you hints on what is happening, the good stuff happens down where the ceramic meets the metal. You have to look deep.
Looks like the center electrode is burnt smooth off.
It's not originally designed for either a 150f or 230f is what I was getting at.
But no answer to my question either?
Looks like it could be an old gold palladium plug or maybe an iridium.
Sorry, It's in a 2007 150f and I'm pretty sure that whatever plug it is, is straight out of the manual.
They more or less call the plugs a fine wire plug. It's a more expensive spark plug that uses much more costly metal for the electrode. Looks like someone at a shop gave you the more expensive plug.
