Original BMW Oil Filter Housing Gasket for BMW 1–7 Series, M2, M3, M4, X1–X6, and Z4 (2006–2021)

This Original BMW oil filter housing gasket, part 11-42-8-637-821, seals the oil filter housing on the N20, N26, N51, N52, N53, N54, N55, and S55 engines in BMW 1 through 7 Series, M2, M3, M4, X1 through X6, and Z4 models from 2006 to 2021. BMW names it simply a gasket, and it weighs 10 g (0.35 oz). This version has been in production since April 2015. An oil filter housing gasket sits between the filter housing and the engine and keeps pressurized oil from seeping out at that joint, .

Original BMW Parts carry a 24-month parts warranty.

The 11-42-8-637-821 number supersedes the earlier 11-42-7-537-293. BMW rates the change as exchangeable retrospectively, so this gasket replaces the older number on every car that used it. The same gasket covers the four-cylinder N20 and N26, the naturally aspirated N51, N52, N52N, and N53 sixes, the turbocharged N54, N54T, and N55, and the S55 in the F80 M3, F82 and F83 M4, and F87 M2 Competition. That shared use means a 2008 E90 328i and a 2016 F30 328i take the same part, even though their engines differ.
