Hi guys,

Too rich? Way over dued for replacement?



There's light brown copper powder around the needle...

Shouldn't it be dark to semi light brown colour when the old ones come out?

That's looking lean and way to much ash or some sort of contaminant in there. It looks like the plugs have been in there for a long time too.
