2020 softail, changed them in 22, then in 24. These are the plugs, one has failed. I replaced then with Drag Specialties ones.
Do you see anything wrong with them? I could not.
One has an internal break. After 85mpg it started to ping, knock, and loose power.
Replaced the plugs and no more problems.

Anyone use these? how do they compare with HDs?
