I just received some sparkplugs from Courtesy...

NGK "PFR6G-11"...the FSM lists "PFR6C-11" as the correct (cold type) plug.

The guy at Courtesy said that NGK replaced the "C" plug with the "G" plug and that it's the right one. Can any of you verify this? I don't want to put in the wrong plugs...

edit:

did some more searching

so it seems like "C" is special ground electrode and "G" is racing use...

still doesn't tell me if it's ok to use on my car tho, so any help is appreciated.
