This is BMW part number 11121741468 (11 12 1 741 468) and is described by BMW as a head gasket for cylinders 1-4 (bank 1) on M62 engine used in 1996-1998 E39 540i, E38 740i, and E31 840ci models. BMW has two gaskets available: original 1.74mm thickness for non-machined cylinder head and a thicker 2.04mm gasket if the head has been machined.
The rest of the gaskets for a M62 head replacement are sold separately (see below).
This is an OEM Head Gasket for M62 engines manufactured by Elring Klinger - an original supplier to BMW for many gaskets and seals. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
