I need to change my spark plugs, so i got some Bosch Super 4 plugs. what sort of rench head do i need to remove the standard plugs? is it just a standard 10mm plug? because it looks like its a different fitment from what i can see....

 

i would get the correct plugs before worrying about the wrench

 

Standard spark plug wrench - though you need a long extention to reach down into the well.
