That's right, here's why. Actually, it's Motorcraft and Visteon Coils. Visteon was one of Fords coil suppliers (COP ignition coils) for more than a few years. Both share the same builds and thermal protection to Ford specifications. About Visteon, coils that were made here are now made in Central Europe, - Hungary to be exact and are still made to Ford Specifications. They can be hard to find, - best place for those are FleaBay or the Amazon.
The two brands mentioned above haven't had any competition for years.
All other COP system coils (aftermarket), even the larger companies- import coils from china and put their color or sticker on them. The bad, - these coils use single wire build magnets and have poor frequency performance (RFI). Also, they lack the thermal protection Motorcraft and Visteon COP system coils have. One little surge can hurt them, shearing enough turns causing low grade misfires to start, then eventually complete failure.
