Title: CHAMPION RN12YC
Post by: plymouthbelvy on October 11, 2021, 07:46:49 AM
I was looking at plugs and noticed there was a Champion RN12YC and a RN12YC6. What is the difference between them. Thanks.

A number on the end of a Champion plug# designates the gap size it was designed for, in this case 6 == 0.060". 

Otherwise it is the same as a RN12YC

Thank you for the info. I couldn't find that info anywhere.
