I took my plugs out last night and while i was at it i tried to identify which coils i had. There is no numbers on them at all. The only thing i did find was a green dot on the metal stems on all of them.

Any ideas?

Denis did a guide -

Not overly clear but the shoulders look like they may be different.

Thanks Stu but iam still no wiser as to which version i have. Do they usually have the part number on?

Yes I think they do.

Look closer, theyre printed in indented writing on the connector.
