The CSF x Rogue oil cooler uses a Bar & Plate construction (vs. tube and fin) in a top/bottom configuration. The Bar & Plate design makes the cooler much more robust and able to take abuse from debris hitting it at high speeds on the road or track. The cooler uses extruded end tanks which means it is a much stronger design than simple bent aluminum sheet construction found on the oem unit. The cooler is a bolt on design for the factory radiator or the CSF High-Performance Radiators (E46 M3 - CSF #7058 / E39 M5 - #7064) and uses the factory oil cooler lines.. The CSF #8032 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.. CSF and Rogue Engineering teamed up to create an oil cooler that could stand up to the rigors of track use while still being a simple and straightforward installation. The new oil cooler is over 2 times larger than the factory unit with a volume of 243 cubic inches (vs the factory unit's 103 cubic inches). This allows for cool, consistent temperatures in the hottest of days driven at the very limit.. While the E46 M3 and E39 M5 come with a factory oil cooler, it was obviously not designed for high performance driving. Just a few minutes on the track quickly shows how inadequate the factory cooler is. Dangerously high oil temperatures can lead to serious damage to your engine and need to be addressed.. CSF offers the best and most advanced Oil Coolers on the market. So when it comes to keeping your engine oil temps down as you push your E46 M3 / E39 M3 hard on the street or track, a CSF Oil Cooler is the obvious choice..
