Of course pretty much everyone knows that certain communist countries steal intellectual property rights and counterfeit U.S.A. manufactured goods and they could really care less about quality. All of the spark plugs that I have for sale have been thoroughly examined (Google how to identify counterfeit ACDelco spark plugs), to insure that these are ORIGINAL and made in U.S. controlled manufacturing facilities. If you don’t think it matters Google that question as well. All of my plugs came from a pallet that I purchased from a friend who has a mechanics shop here in Denton. They are the real deal and with hundreds sold I have had zero complaints.
