do88 performance intercooler designed for an easy drop-in-fitment in your BMW M2 / M3 / M4 F8X
The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an “regular”; air-cooled intercooler. This OE intercooler has a Tube&Fin core with clamped plastic end tanks. This construction has its drawbacks since it is prone to crack and start leaking coolant into engine or leaking boost pressure out of the tank sealings.
The final design resulted in a bar-and-plate core with TIG-welded aluminum casting end tanks. This offers a peace of mind for any High boost tune. They have managed to utilize a massive core 85% larger than OEM and decrease (16% lower) the charge air pressure drop and maintain drop-in installation without modifications. Decreasing the charge pressure drop over the intercooler has several benefits such as the turbos needs to work less to achieve target boost / lower temperature / improves throttle response.
