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.
