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

. Prime Ave washers are significantly smaller in both outside diameter and overall thickness. My biggest concern is the lack of thickness. The inner diameter is correct, but that's about it. They are aluminum but I can't tell if they are the same quality of aluminum or not. All in all, I cannot recommend this product. look elsewhere
