This is one of the 2x Gaskets required for the Oil Cooler Assembly.
There is two of these needed, and they are both different. Generally both are required to be replaced when the oil cooler assembly is removed.
these Seal the Cooler assy into the Cooler housing.
It is common for the Oil Cooler Assembly on the side of the Engine to leak, and just replacing one of the Orings normally doesn't do the trick, it is best to replace the whole oring and gasket set.
We sell this as a complete set with the 2 Orings, 2 gaskets and and the main housing gasket
there is an alternate part number for this gasket which is 2133430J00- this is a better gasket as it has an Oring built into it for extra sealing, but it is not always available,
