Mosselman Twin Oil Cooler Kit, BMW 1-Series E8X

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:

Mosselman Oil Thermostat: N54

*E Series BMW Models with an N55 engine require the N54 Oil Thermostat*

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.

FITMENT: 

BMW 135i E82 N54 306HP

Note: This item is not ''plug-and-play''. You will need to make some adjustments to the car to fit the bigger oil cooler and bracket. Additional OEM products that you need for the installation are: oil cooler front air duct (left), wheel arch air duct (left), inside wheel arch for the auxiliary cooler (left).

​Installing the twin oil cooler extension on a BMW 1M requires some extra modifications to make the left oil cooler fit into the car. The 1M is equipped with an auxiliary water cooler on the left side of the car. This is the place where the second oil cooler needs to be installed. To make this fit the auxiliary watercooler has to be removed and probably a bigger radiator has to be installed. It will add extra time to the installation process.
