Forge Motorsport has a long and proven heritage in the development of high-performance components across every generation of the BMW MINI platform. As the chosen manufacturer for the MINI Challenge race series, we bring unparalleled knowledge, engineering expertise, and real-world motorsport experience to every product we design. This background allows us to consistently deliver some of the most advanced and performance-focused upgrades available for MINI vehicles.

FMINT37 is Forge Motorsports performance intercooler (replacement for OEM part 17519846916) which features an enlarged stepped-core design which dramatically increases heat-transfer efficiency, allowing this cooler to dissipate heat more effectively from compressed intake air. Lower intake air temperatures result in denser air entering the engine, improving combustion efficiency and reducing the likelihood of detonation. The result is stronger, more reliable power delivery, even during sustained high-load usage where stock intercoolers are prone to heat soak.

Design and product evolution

Using a combination of advanced 3D scanning technology and traditional precision measuring methods, Forge Motorsport developed an exact digital model of the vehicle to ensure a perfect fit and optimal performance. This initial design was then extensively refined by our Computational Fluid Dynamics (CFD) engineering team, allowing us to optimise the end tank geometry for maximum airflow efficiency.

The resulting end tank design incorporates a cast alloy construction with internal air guides that ensure the charged air is distributed evenly across the entire intercooler core. Without this critical internal shaping, compressed air naturally follows the path of least resistance, flowing predominantly through the lower section of the core and leaving the upper portion underutilised, leading to elevated intake air temperatures. Forge’s engineered airflow management ensures full core utilisation, delivering significantly improved thermal efficiency and reduced IATs (Inlet air
