Hi John... According to the RSR Manual the correct Spark Plug is a Bosch X310 P21, I think a friend has a couple of set's floating around. and time permitting I will post a few reference photo's.

Yes, they do use a 15mm hex nut instead of the allen nut on the head stud nearest to the 2nd spark plug.

Could you list the spark plugs that were used in the RSR?

Also, how difficult is it to install the lower plug and did they use the normal 911 head
allen head fastener or did they need a normal hex nut near the second spark plug?
