MMX Performance BMW Oil Filter O-Ring Service Kit - B58 / B57

The MMR Performance Oil Filter O-Ring service kit is a direct oil filter o-ring replacement designed specifically for servicing the MMR Performance oil filter and billet housing. This kit includes four precision oil filter o-rings required to maintain a proper seal and consistent oil pressure during regular maintenance.

These oil filter housing O-rings are essential for preserving the sealing integrity of the filter system over time. As O-rings naturally degrade with heat cycles and oil exposure, replacing the O-ring for the oil filter housing during filter cleaning or servicing helps prevent leaks and ensures optimal performance.

This oil filter cap O-ring kit is a direct replacement for the original seals supplied with the MMR Performance oil filter, making installation quick and straightforward. No special tools are required - simply remove the worn seals and install the new O-ring oil filter components in their original locations.

Important:

Includes four oil filter O-rings only

Does not include the MMR oil filter or billet housing

Fitment is limited to the MMR Performance oil filter (MMR17-1502), designed to prevent the well-known B58 oil filter collapse issue

For best results, we recommend replacing your oil filter O-rings regularly whenever the filter is cleaned or serviced.
