Part number 111 26AA 000 fits my 2003 naturally aspirated 2.5 liter Subaru Forester with automatic transmission oil drain plugs. I decided it was time to service the automatic transmission at 117,000 miles today (4th service) and found that they were a perfect match for that drain plug as well. This washer combined with Shell 5w-30 Synthetic (SUV and Truck) and Mobil 1 1-108a Oil Filter will keep my engine oil full and clean for 10,000 miles. This flushing disc combined with Valvoline Maxlife Synthetic ATF and Mobil 1 1-104a Oil Filter will keep my transmission clean for the next few years or 30,000 miles.
