The E-series N54 and N55 engines are no strangers to oil cooling problems, that's why we developed the Mosselman Oil Cooler Kits. The higher capacity oil coolers ensures that E-series models equipped with N54 and N55 engines stay cool, even during heated conditions. We strongly advise combining the cooler kit with the Mosselman Oil Thermostat:
*E Series BMW Models with an N55 engine require the N54 Oil Thermostat model*
The Mosselman Oil Cooler Kits for the BMW 1-Series E8X and BMW 3-Series E9X are available as single or twin cooler kits. The twin cooler kit replaces the OEM cooler on the right side of the car and adds an extra cooler on the left side. The kit comes with the 2x Setrab 19 row oil cooler, 2x stainless Mosselman bracket, 1x Mounting bracket, 1x Oil adapter AN8, and a hose kit (3 hoses). The Mosselman Oil Thermostat has to be ordered separately.
