Is a J8C spark plug the same as a J8 ?

[AC_B-1Novice 1]

My briggs engine had a J8 plug in it and it went bad. All I could find was a J8C to replace it with, no J8's. Is this ok or should I keep trying to find a J8? Larry

The J8C is the same as a J8 except it is the newer "Copper Plus" design (hence the last digit is a "C"). All the dimensions are the same (thread size and length, electrode reach, etc.) The J8C is even a little more efficient than the older J8, so go ahead, and enjoy!

As long as we are on the subject of spark plugs, what is the factory recommendation for a K321 14 horse Kohler. Any personal preferences?
