Our first choice is MANN OIL FILTER.
Almost anything from Europe gets a Mann. The media and housing structure are surpassed by no other filter. The drain back valve is a coil-spring loaded metal conical disk with a thin sheet of rubber acting as a gasket between the metal valve and the base plate.
The filtering medium is carefully and evenly set between finely finished endplates, and is packed in tightly. The overpressure valve is a coil spring loaded, with rubber gasket mechanism - built into the far end of filter housing.

The second choice is BOSCH or MAHLE OIL FILTER . Bosch Premium Oil Filters, featuring Bosch FILTECH, utilizes an exclusive blend of natural and synthetic materials to provide superior oil filtration and increased engine wear protection. The Bosch FILTECH filtering area is up to 42% larger than conventional filters. The filter media is close to 30% thicker, and can screen out more harmful contaminants than a conventional filter. It has stronger steel base plates and housings. Also it has clean side anti-drain back valve built in. This valve ensures a supply of clean oil when the car start.
The MAHLE filter has similarities with the BOSCH filters. The similarities are that is has the spring loaded anti-drain back and bypass valves built into the cartridge end caps. The differences are that the bypass valve has no steel plate (it is a thick piece of spring-loaded rubber) and the anti-drain back valve has a wider steel plate than the Bosch. Also, a coil spring spacer is used instead of the leaf spring and the filter element has a metal seam instead of a glued one. In our opinion, these differences do not make this filter better or worse, it is just different design.
Engine oil lubricates all the moving and functional parts in the engine. As a result of combustion, particles of dirt and combustion residue such as soot escape into the engine oil. They contaminate the oil and make it more viscous.
This means that the oil supply is not adequate and protection from corrosion can no longer be ensured.
As a result, engine performance is impaired and fuel consumption increases. In the worst case, the engine could be damaged. Increasing engine performance and at the same time reducing fuel consumption places high demands on engine building. Only clean oil can ensure that engine performance remains consistent.
This is where the full effectiveness of a MANN-FILTER is really brought to bear.
BMW's filter house is manufactured by MANN. This is why we use MANN oil filters. Long service lives and low maintenance costs are taken for granted with today's internal combustion engines.
High-quality oil filters ensure that motor wear is avoided and that the oil quality is preserved.
Oil filters have the task of holding back any dirt in the lubricating oil loop in the engine, which causes early wearing of the bearings.
