Motocraft Double Platinum Plug

I need some clarification on this issue.

It seems after a check at RockAuto for Motorcraft plugs and reading this thread the original Motorcraft double platinum plug, awsf3xpp, has changed to a new plug, agsf3xfm. It also seems this new plug is no longer a true double platinum. Am I correct in my understanding?

Thanks..
 
motorcraft.com still lists the same number. I would check with them first. Oh wait, g is for Platinum, w is standard. Looks like they are right
 
digitalchaos - your are correct - i just went thru this myself - the updated motorcraft plug IS NOT a double platinum. just get the autolite equiv to the original motorcraft number and you will be ok. depending on how much you modded the motor you might want to consider going one heat range colder. solved my detonation problems.
