Re: Yet another question about plugs....!
Just when it seems all simple…How to pick the right Motorcraft plugs!?
My manual lists part #AGSF-34FP ; which evidently has been replaced - a thread on another forum noted that the new number is SP-440…
Rockauto lists SP-498 (platinum) and SP-412 (nickel)
Summitracing lists SP-432 (narrowing down Motorcraft plugs to '08 Ranger Sport–trying to eliminate 4.0 OHV from the equation–their plugs are different iirc)
Does anybody know the difference between the 498 and 432 plugs? I'm tempted to just go with Rockauto (I'm already getting a stack of other parts)
