As has been the case with every other OS plug I own these continue to be my go-to for consistent tuning, excellent performance and unusually long life. Even a rich tune will have difficulty fouling these plugs. I don't know the first thing about a race tune, but as a basher, these plugs are exceptionally forgiving.
