Review on 🔌 Universal Precision Car Spark Plug Gap Tool with Threaded Spark Plugs, Billet Aluminum Caliper (14mm) by Edward Freeland

available THREE main problems with this tool, 1 fixable and one not. This means that the end has uneven threads and an uneven surface, making it impossible to apply even pressure to the tip of the spark plug. This means the gap will also be uneven. This can be fixed. But it doesn't need to be fixed at all. The second says it's designed for 14mm threads. I don't know what metric system they used, but the spark plug threads didn't even come close. as shown in the picture. It will be sent back. Pure Chinese production. Probably a knock off of a higher quality tool with no actual use testing.
