The MMR Performance intercooler for the F20/F30 M135i and M235i improves power and torque output significantly by substantially reducing charge air temperatures versus the OE cooling setup. Using a huge tube and fin stepped core, our performance intercooler provides almost double the core volume of the OE unit and a frontal area around 70% greater than OE, too. The core itself uses internal turbulators to improve its cooling performance and the CFD optimised end tanks assist with maintaining the best possible airflow across the core. Despite the huge core size, due to the tube and fin construction the competition unit only weights 8.6kg whilst still providing the best solution possible when power output and low air charge temperatures and minimal pressure drop are required. FEATURES 520mm x 215mm x 145mm tube and fin stepped core 70% larger frontal area than OE 90% more internal volume than OE Delivers substantial temperature drop across the core, with minimal impact on pressure drop Anti-corrosive thermal coating Easy installation, not cutting or permanent modification to the vehicle required Please note this will not fit the convertible models.
