The IW20 plug is a Denso product. If you are looking for the NGK Iridium IX, it is the BPR6EIX. This plug is quite common for European autos:

My used Joyner 650 did not come with a tool kit. I wouldn't care, but I cannot fit a standard deep well socket over the spark plug. Is there a special tool for this? My sockets are not clearing the walls of the head.

I'm glad I wasn't doing anything stupid. I have multiple 13/16" and 21mm deep sockets - After trying four different sockets, I was sitting around like a monkey just scratching my head.

Did your Joyner come with a tool kit? Where did you get your box spanner? Time to get another one-purpose tool...
