HIGH-PERFORMANCE INTERCOOLER
BMW 320D E9x I N47

The MMR High Performance Intercooler for the N47-powered 320d improves power and torque output significantly by substantially reducing charge air temperatures versus the OE cooling setup.

The MMR Performance High Performance Intercooler is a direct-fit replacement unit that uses a super-efficient Tube and Fin core specifically engineered to support maximum performance gains on N47-powered 2.0 120d, 123d and 320d.

With the right modifications, the N57 diesel is more than capable of producing good power, but the additional heat that generates is often enough to overwhelm the standard cooling setup, showing up as serious power losses during hard driving as air temperatures soar, and long recovery cool-down times needed.

Using a large Tube and Fin stepped core, our performance intercooler provides literally double the frontal area and almost 40% more volume than OE, too with minimal pressure drops. The core itself uses internal turbulators to improve its cooling performance and the CFD optimised cast end tanks assist with maintaining the best possible airflow across the core.

Despite the large core size, due to the Tube and Fin construction, the Intercooler weights just 5.4kg whilst still providing the best solution possible when power output and low air charge temperatures with minimal pressure drop are required.

Our development focussed on finding the ‘sweet spot’ of maximum IAT cooling versus minimum pressure loss. This has allowed us to achieve increased size without increased lag.
