Dipstick Tube O-Ring, Upper, 20x2.5mm - E46 325i M56 SULEV

This part is listed by BMW as BMW part number 11437519850 (11 43 7 519 850) and is described as the upper 20x2.5mm o-ring used on the dipstick tube for M56 SULEV engines. To better contain oil/fuel vapors, the M56 dipstick tube has a second o-ring seal. This is in addition to the usual o-ring used where the tube enters the oil pan.

This is a Genuine BMW o-ring with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
