Genuine BMW dipstick tube oring. This is commonly used on the steel sumps of vehicles with an N52/N52K engine and manual transmission, and N52 engines (silver top) with automatic transmission.

Replacement required upon removal of dipstick tube from sump. Replacement is recommended in conjunction with a sump gasket replacement. We also recommend replacing the oil separator return duct which often shatters upon removal.
