Review on Pack of 20 Prime Ave Oil Drain Plug Washer Gaskets for Mazda Part# 9956-41-400 - Compatible and Sealed by Corey Bigglesworth

Just installed on a 2017 Mazda 6. These seals look and feel just like the original. Fits perfectly. And let's face it, it's just aluminum spacers/washers. As long as they are the same size, OEM or aftermarket is the same. Update 08/14/2019 After 2 weeks I noticed oil stains under the car. I had my suspicions and upon checking I found that the oil was dripping out of the drain plug very slowly. This has never happened to me when using an OEM gasket. I replaced it with OEM. In fact, the flow has stopped. I don't know what's wrong with them, but something about them caused an oil leak. I'm going back to the OEM for now.
