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 for BMW, this 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.
