Review on 🔧 High-Quality OEM BENEDETTO Auto Service Oil Drain Plug Gaskets/Crush Washers (10 PCS) - Replaces Toyota 90430-12031 Aluminum (QTY10) by Mac Sterling

Looks like genuine Toyota OEM parts. Good quality. If you change the oil yourself, you should buy them. At less than $1 each, this is a cheap but necessary part to ensure the oil drain plug doesn't leak. I have personally known engines that have failed due to leaks causing low engine oil levels. Always keep a bag of them handy. If you run out, order another pack in advance.
