I have used Champion UD 16 for years on my '37 21 stud. Getting ready to tune up. Any reason to look at any other plugs?

We've had this discussion before, but here goes. I gave up on Champions long ago. I switched to Autolite 386's. Reasons # 1 They don't gas foul like Champions. #2 They can run hotter. #3 They last lots longer for the reasons in # 1 & 2 above. #4 They are black instead of silver and look nicer and stay cleaner on the outside too. #5 All around better performance. 1934 Ford's since 1972 This message was edited by 1934 Ford on 3-31-15 @ 7:02 AM
