EPMAN CNC Aluminum Oil Filter Lid Cap with Oil Cooler Fittings for BMW M52 M54 M56, Silver

Key Features & Benefits – BMW M52 M54 M56 oil filter lid cap with oil cooler fittings silver

The BMW M52 M54 M56 oil filter lid cap with oil cooler fittings silver is a CNC aluminum adapter cap that lets you add an external oil cooler without replacing the complete oil filter housing. It is made for BMW M52, M54, and M56 engine applications, commonly on E36, E46, E39, E53, and E83 platforms, and it uses 2x AN10 fittings.

The dedicated sealing design routes oil toward the cooler lines and through the oil filter. The 2x 1/8" NPT sensor ports and silver anodized finish also make it useful when the build includes separate sender locations for additional instrumentation.

When is this useful?

This layout is useful when you want to add an external oil cooler to an M52, M54, or M56 engine, or when you need separate oil system pickup points for compatible temperature and pressure sensors.
