I got my plug today. It is a Dorman 65407 M14-1.50 for VW Beetle, Golf and Jetta. I think it will fit since it looks to be the same as the VW plug.
BTW, the M14 crush washers seem to fit the plug as well.
The FJ09 looks better without the handguards. And by the way what kind of side stand "foot" do you have? Does it come into contact with the centerstand or anything.
Napa 1365 will no longer fit the FJ-09. This filter must have had a design change.
