Are AGSF-32FM plugs single or double platinum? I get conflicting information. I know the PP plugs do not exist, and the plug numbers changed. If not, what is a true double platinum for these cars?
I've got 30k on the 32FM's, and I am part way in there already, thinking about changing them. The one I pulled looks pretty good, one dark spot on one side of the ceramic. The original PP's, at 65k, looked pretty rough when I changed them 5 yrs ago, and the difference in throttle response was noticeable afterwards.
I've always changed plugs at 30k in our other MN-12's, but I used Autolite 103 copper plugs.
Thanks,
Al
