Dinan High Capacity Oil Cooler System for BMW 135i 2008-2010 E82 E88
Keep your BMW 135i cool, consistent and fast. The Dinan High Capacity Oil Cooler System is the go-to oil cooler upgrade for the 2008, 2009 and 2010 BMW 135i Coupe and Convertible E82 and E88. If you are running higher boost, tuned power, spirited driving or track days, an upgraded performance oil cooler is essential to control oil temperature, prevent heat soak and protect your engine under sustained load.
This genuine Dinan oil cooler provides dramatically improved thermal efficiency over the factory unit. It delivers twice the oil volume of stock and vastly more tube area for heat rejection. The result is stable oil temps and consistent performance lap after lap and pull after pull, even in high load and high boost scenarios.
