Pulled the drivers side rear plug yesterday and it looked brand new. Was ACD platinum and the # on it was 952.
The replacements I bought are also AS Plat but they are #'ed 933 and they appear to be about a 1/16 of an inch shorter (thread to tip)
Engine is a 383. What's the dif between the 952 and 933? Is it the heat range?
Thanks

I am sure it is heat range, That seems like a lot though.
