Do88 E9X M3 Performance Oil Cooler

Every e92 m3's which sees trackwork should be swapping out two things - their engine oil cooler and their DCT Transmition oil cooler if the car is with a DCT gerabox. We always recommend the engine oil cooler change first. The stock oil cooler is sufficient for road driving, but it cannot keep up on hot days, while doing multiple laps on track and we ourselves have seen oil temperatures get into the 180 degrees Celsius and above zone which is not a good idea when it comes to a performance engine with known bearing wear issues. 

This is why we no matter if you are a track day enthusiast, an endurance racer, a time attack racer, or a spirited road driver, we wholeheartedly recommend the Do88 E92 M3 drop-in oil cooler which is, we believe, the best such product for the vehicle on the market.
