Original BMW VANOS Pressure Valve Filter Cartridge for BMW E46 M3, Z3 M Coupe and Roadster, and Z4 M Coupe and Roadster (2001–2008)

On S54-powered BMW M cars, VANOS oil passes through this Original BMW filter cartridge, part 11-36-1-401-971, which mounts on the end of the VANOS pressure limiting valve in the E46 M3, Z3 M, and Z4 M from 2001–2008. BMW calls it simply the filter cartridge. Its job is to keep contaminants from reaching the VANOS, which depends on steady oil pressure to adjust the camshafts correctly. The part is made in Germany and has been in production since February 2000. Like any small inline oil screen, it traps debris before it reaches tight passages and solenoid valves downstream.

Original BMW Parts carry a 24-month parts warranty.

This cartridge belongs to the S54 VANOS system specifically, and BMW's data ties it to the E46 M3 including the CSL, the Z3 M3.2 S54, and the E85 and E86 Z4 M3.2. Replacing it every 30,000 miles limits contamination and supports VANOS service life.
