CSF 2014+ BMW M3/M4 (F8X) Top Mount Charge-Air-Cooler - Crinkle Black

When you're pushing your 2015-2020 BMW M3 or M4 hard, especially during track days or repeated dyno pulls, you might notice a drop in power. This is a common issue known as heat soak, where the factory intercooler can't keep up with the heat generated by the turbos. What you get with this CSF charge-air-cooler is a direct replacement designed to significantly improve your car's ability to manage intake air temperatures. It's a well-built unit that works with your car's existing systems to keep things cool and your engine running strong.

This CSF charge-air-cooler is built with a core that's 60% larger than the stock unit. This increased size means it can transfer more heat away from the compressed air coming from the turbos, directly reducing intake air temperatures. It features a unique dual-pass, cross-flow design with multiple air dividers in the cast endtanks, all analyzed with CFD to ensure the air moves efficiently through the core. This setup is a big improvement over the factory's single-pass vertical flow design. The unit comes with a professional crinkle black powder-coated finish, giving it a solid look that complements the engine bay. It's designed as a direct, plug-and-play installation, using OEM-style quick-connect fittings for the coolant lines and sensor ports, making the swap straightforward.

This charge-air-cooler is the first of its kind for the BMW S55 engine, utilizing 3D scanning and rapid prototyping to ensure a precise fit and maximum surface area utilization. For the best results in keeping intake temperatures down and power up, it's recommended to pair this with the CSF Front Mount Heat Exchanger (CSF #8075). This combination works together to dissipate heat effectively, helping your M3 or M4 perform consistently even under demanding conditions.
