Spark plug colour - gti6man - 21-07-2017
I've just gave my 6 a service and changed the plugs just wanted to know what sort of colour the plugs should be after about 20k? Looking online this may indicate it's running a little lean or is this to be expected?

they look fine.
most of the guides for plugs are for carb cars usin leaded fuel.

Yeah yours look fine, as said by others.
Here's my recently changed iridium's from a 103k TU5JP, plugs have roughly 20k miles on them.
