They are only slightly better than the old ones IMO, I wouldn't rely on them without carrying an NGK for backup. We still supply genuine NGK plugs with all DLE engines we sell.
I was really only curious for other people around here .... I have a good supply of NGK plugs and rarely change one anyway. It is hard for people to understand when you tell them to throw away the plug that just came with their new engine then install a new CM-6.
