I’ve used over sixty of the black Ebay Zhongfadz coils now without any failures. Most of these were installed on my own motors with a few on other peoples motors and no one has come back complaining yet. Knock on wood!
A couple of Amazonian ones I picked up a month or two back were green and I could swear they came out of the German Prufrex molds. The ohm readings on these ones were higher than OMC/BRP coils, around 7.8K, just like the black ones.
