Hello List, been gone for a few months.
Just installed new plugs in my 84 westy. I purchased them from one of
the list vendors. The plugs I took out were Bosch W7CCO and the ones I
installed were Bosch W7CC....  Are these two different temperature plugs
and if so which is best for driving in warm weather?

TIA

Bob
