This oil filter housing cap is constructed from high-quality billet aluminum, complete with a black anodized finish for added corrosion resistance. Designed specifically for the S54, this lid replaces the OE part and accepts the OE o-ring.

The M50/M52/S50/S52 engines are notorious for their well-documented problems stemming from harmonics. The vibration leads to the oil pump shaft becoming weak, causing it to either break or the oil pump nut to loosen and fall off, resulting in an immediate loss of oil pressure. Worry no more! 5150 has the solution! At the core of this kit is a hardened Chromoly shaft, meticulously centerless ground to guarantee absolute precision. This shaft is designed with an exclusive square key lock system, which not only prevents the gear from ever rotating on the shaft but also reinforces the mounting area, adding additional strength. Furthermore, we replaced the problematic oil pump nut with an extended-length bolt, which is EDM drilled to accommodate safety wire for a secure fit in all conditions. Don't wait until your oil pump fails, leaving you facing expensive engine repairs! Key Features: Centerless ground shaft made from hardened Chromoly. Bolt with EDM drilling, including safety wire. Grade 8 extended-length hardware for secure gear attachment. Left-hand threaded to prevent unexpected loosening. Double-D keyed shaft and drive gear. Fully serviceable and rebuildable without the need for grinding.

Metal drain plug featuring a magnet that traps ferrous metal suspended in your oil. These magnetic drain plugs trap tiny particles that are unable to be caught by your oil filter, leaving you with a cleaner engine, and over time, saving your bearings and oil pump from unneeded wear.

This is the replacement OEM oil filter kit for the S54 engine, as used in the E46 M3, Z4 M Roadster and M Coupe, as well as the 2001-2002 MZ3 M Roadster/Coupe (with S54 engine). This is the complete oil filter kit - filter, large o-ring for filter housing cover, small o-ring for bolt seal, flat washer for bolt, and copper seal ring for the drain bolt. It's everything you would need to complete an oil change - minus the Castrol 10W60 oil of course, which we sell at a great price. This kit is manufactured by Mahle - the original supplier to BMW for the 11427833769 BMW filter (factory filters come with the Mahle part number OX 187 printed on the cap).

Why Mahle over Mann? In the past we have sold a few different oil filters for the E46 M3 and S54 engines. But Mahle is the true OEM supplier for this part number. It fits perfectly and is the exact replacement part at nearly the same price as the slightly different Mann filter (and less than the factory BMW filter). For more detail, click here.

This filter fits the following BMWs:
2001-2006 E46 M3
2001-2002 MZ3 - M Roadster & M Coupe (S54)
2006-2008 MZ4 - M Roadster & M Coupe
