I ordered some replacement plug's for my 94 "Motorcraft agsp-32c" package arrived and received these agsp-32ca plugs, are these a updated version or is it a **** up? These are the one's i ordered https://lmr.com/item/AGSP32CK/1979-95-Mustang-Motorcraft-Spark-Plugs-Aftermarket-Heads

What's different about the new plug from the old plug?

The obvious is color. Be sure seat length, tread pitch, and overall size is the same. The "A" within the part # may just represent plating.

They do appear to be same size, I did a search on multiple auto part's store's to see if they were compatible with a 94 and they weren't lol so idk. All i know is if you look at the lmr page it say's exactly what come's in the box which is agsp-32c, even a past customer's photo of the spark plug box has same part # lol.
