I have been switching as needed over to the NGK plugs, but have recently noticed there have been 2 plug numbers recommended: 3112 & 3212. Which one is correct???
Thanks for the help!
 
The one you want is NGK B4L, which is stock number (part number) 3112. Much better than Autolite or Champion, IMO.
