Yes only better. Maybe just a tic colder than a Nova. I'm telling you, Nova plugs made in the last 1 1/2 years or more are junk. They used to be fantastic but not anymore.
I'm going to have to give the OD plugs a shot. Everyone that runs them says they are great but they are almost all off road guys.
