AC_B-1Novice 0 Report post Posted July 5, 2010 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 Share this post Link to post Share on other sites
Guest Report post Posted July 5, 2010 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!

Brettw 383 Report post Posted July 5, 2010 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? Share this post Link to post Share on other sites
