Oil Cooler

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.

Doing a cooling system refresh, or just replacing worn out and soft old hoses? Why settle for stock when you can get the added life and heat tolerance of silicone hoses? Retains OEM fitment without the OEM hose flaws, silicone will resist breaking down and getting soft as coolant heat cycles and will last longer than the OEM rubber hoses.

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!
