if you say so. electricity always wants to take the path of least resistance. so if it only takes 4000ohms of resistance to jump from the plug wire to the engine block. THATS what its going to do. RFI interferance was an issue with 70's tech, but not anymore. don't believe me? put non-r plugs into any modern car (if u can find the app). nothing bad will happen.
its all about getting the spark to the ground electode.
