Re: AC Delco R43 Spark Plugs

I also agree with Rich (Mr Chevy) that the newer AC R43 plugs like the ones you have Bart, aren't very good. If you want to run the correct plug that your car is supposed to have, then look for a set of vintage AC R43's like these with the 4 green rings....they are much better than the ones you have.
