Many, many years ago, I used to make deliveries to the Ford Engine Plant in Lima OH. They made or make many well-known Ford engines including the 2.7L Ecoboost today or the 3.0L Vulcan (went in the Taurus, as I recall). I've seen truckloads of "DENSO" parts unloaded there to be used on the engines they made. Of course, it could have been ignition coils, spark plugs, any number of sensors, fuel injectors, and so on.The Denso ignition coils had the motorcraft part number and logo printed with just a Denso sticker put on top.
