Review on 🔧 Honda Genuine OEM Automatic Transmission Drain Plug Washers (18mm) - Pack of 5 High-Quality 90471-PX4-000 by Angel Cortez

I'm shocked. At first glance, the inner diameter appears to be much larger than the OEM disc, but when I held them side by side they were the same in both inner and outer diameters. This is definitely a 5 star product considering it is half the retail price. If you change the ATF on every other oil change on all of your vehicles, it's worth buying in bulk.
