The most common plug for cags that I have seen is the F7RC. Below are the direct replacements for that plug.
BR7ES is the NGK direct replacement for that plug.
W22ESR-U is the DENSO direct replacement for that plug.
WR5CC & WR5CP are the BOSCH direct replacement for that plug. (both are listed, unsure why)
RN3C is the Champion direct replacement for that plug.
Note - this information was gained from manufacturer sites yet those sites quote that the numbers given may not be correct. If you are unsure how to compare plugs please ask for help when purchasing at a reputable and knowledgable dealer.
