Nothing to do so I'll pull out my plugs and have a look. Only I don't seem to have a socket that fits inside the hole that the plug lives in. So, what size is it? Jeeze I hate winter.

5/8 or 16mm
Should be one in oem tool kit.

Socket

It's an 18MM and as he said, there's one in the factory tool kit.

I found a long slim one at Harbor fright that works well for our plugs.
