I just have the stock 135i Oil cooler. But during my build with everything being apart ill def add the secondary oil cooler so everything is OEM quality. But just trying to decide if im going with OEM or just upgrade to ER competition oil coolers.
How much are the OEM parts to add the secondary oil cooler?
