If you look at a Champion spark plug you will see rough cut threads, elecrodes that are not true, genneral poor quality manufacturing. NGK are made to a higher level.
I just bought a used 8HP evinrude, in which the PO was having trouble getting it to run smooth. Instead of taking it to a dealer he sold it off cheap. He had put in new Champions. I started it up in the dark and could see one of the plugs lighting up the porcelin. (defective from new) I put in NGK's and problem was solved for $5
