I was reading my plugs and they looked like they were one range too hot, its a supercharged application, so im reading the part number it says agsf 32c, now i asked for 93 cobra plugs and they gave me these, i checked and it seems like they use awsf 32c, does anyone know what the difference between the G and the W is? some people say its the threads on the plugs, thanks

its hard to explain but they still have the sam installed lenght, both have the seat in the same place where they seal to the head , its just one has more thread depth.
