The CSF Intercooler for the E82 135i, 1M, and E90, E92, and E93 335i is larger to take advantage of the surface area on the front of the E82, E90, E92, E93, and Z4. It uses a stepped design to maximize surface area. With more surface area comes more cooling capability and the CSF has 85% larger area for 60% more air volume compared to the stock intercooler. CAD and FEA design has optimized the air flow into and out of the heat exchanger and CSF uses rounded front fins that are more aerodynamic than flat. There is less pressure drop than stock which means air velocity stays high. The CSF intercoolers use their B-shaped tube design that can be thinner metal and has more surface area than other tube and fin designs.
