Oil Cooler for BMW 3 Series E90 (2006-2011)

Clear BMW chassis

Please ensure your correct model is selected

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

Kit contents:​

Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)
Low temp thermostat spring

BMW's N54 & N55 engines are very capable motors, but one drawback can be high oil temps. Even on vehicles with a factory oil cooler, oil temps can start to run away during extended track sessions or in very hot climates. This can lead to reduced horsepower, unintended engine and bearing wear, and even complete engine failure if not properly handled. ECS Tuning has an answer for just this problem, a Performance Oil Cooler Kit. This kit is easily installed behind the kidney grilles in addition to the stock cooler (located in the lower front bumper), receiving significantly higher amounts of fresh air and doubling the cooling capacity! Kit Includes: Oil Cooler Radiator Two Braided Oil Lines w/ AN Fittings Oil Distribution Block w/ AN Ports Distribution Block Mounting Bolt NOTE: Installation of the oil cooler radiator may require drilling out mounting holes depending on the selected location. Mounting hardware for the oil cooler is not included. Professional installation is recommended!

The turbocharged E9X 335i is renowned for its excellent performance and the ability to custom tune for more horsepower. Unfortunately, it is also known for oil cooling deficiencies that can reduce horsepower output and potentially compromise engine longevity, especially when driven enthusiastically or when boost is increased. To help maximize the power of your BMW, this FTP Motorsport kit adds a second oil cooler behind the kidney grills in addition to the factory oil cooler. This not only increases the cooling capacity, but more than DOUBLES it! Our kit provides the factory oil cooler with much more airflow then what is available in the fender wells. Only for vehicles with factory oil cooler
