DO88 Oil Cooler

Keeping your BMW's engine oil temperatures in check is extremely important. Temperature fluctuations in engine oil can lead to excessive wear and tear on critical internal components such as the pistons, turbos, rod bearings, main bearings, and more. Many BMWs come from the factory with a stock oil cooler, but these often are damaged from rocks, dirt, and other road debris and must be replaced to maintain reliability and consistent oil temperatures. For those looking to track their vehicle more than a handful of times a year, we recommend upgrading your oil cooler to an aftermarket alternative that allows for greater heat dissipation and increased oil reserves. This will help keep oil temps low even after extended track sessions, keeping you on the track longer and reducing downtime.
