I went to the Ford dealer yesterday to get some new spark plugs for my Ranger. I gave the parts guy my VIN and told him to get me the same plugs that came on the truck from the factory. He didn't have plugs in stock, so I had him order some and I prepaid for them. Looking at the invoice, I saw he ordered part # AGSF24N. I looked online later and it appears these plugs are nickel-coated copper plugs, and my truck has platinum plugs. I later removed one of the plugs from my engine and sure enough, I have part # AGSF24PM. I know for a fact my plugs are the factory-original plugs, since I've owned the truck since it had 12k miles. I looked up plugs at fordparts.com and the only plug they list is the nickel ones, so I guess that explains why the parts guy ordered those. I tried looking up the AGSF24PM plugs, but the website doesn't even recognize that part #. Has that part # been superseded? I haven't been able to find that part # to purchase on any other website either; I can only buy equivalent plugs that have been cross-referenced from that number. And the cross-referenced equivalent plugs are not compatible with my engine according to every website I've visited?? I never knew buying spark plugs could be so confusing. I just want the same platinum plugs my truck already has. They're a pain to change and I don't want to do this job again anytime soon. Truck is a 2006 Ranger with the 4.0 SOHC V6.
Can anyone confirm that the plugs the parts guy ordered are copper, and what is the correct part number for platinum plugs?
