Has anyone seen this ? Went to change my spark plugs and number one had this on the spark plug. I've never seen a plug half shaded like this.

From what I've read on this site the spark plug gap should be .045"and that the underhood sticker for ignition specs is wrong when it reads .035 in.
The California car could be different.
I have it bookmarked as Gap matters 0.045 FYI.
