Controlling heat and lowering intake air temperatures is very important when tuning the F87 M2 S55, F80 M3, and F82 M4. Higher intake air temp (IAT) means the engine computer has to dial back the boost and ignition timing to prevent detonation and knock. BMW tried to control IAT with a more advanced air-water cooling system. The problem that many tuned M3/M4s experience is the factory intercooler is just too small and extreme heat overruns the system. The low-production M4 GTS received a water injection system to further control IAT with more boost. But a simpler, bolt-on S55 intercooler upgrade is this CSF Dual-Pass design.

The CSF uses a 60% larger core for greater resistance to heat soak. More surface area = cooler overall temps for extended time. The Dual-Pass design gives the intake air more cooling capacity than the original single-pass design. And the CSF is a direct bolt-on replacement to the stock intercooler. All of the original hose connections, chargepipes, and fittings are an OEM-like fit.

The CSF top-mount uses aluminum end tanks that are stronger than the original plastic pieces on the stock cooler. They are also CFD test and cast construction for optimum flow in and out of the core. Multiple finishes are available - subtle wrinkle-black finish or unfinished if you plan on customizing the colors of your engine bay. Other finish options are also available (inquire).
