CSF High-Performance Charge Coolers for BMW F90 M5 & F92 M8 (World’s First Cast End Tank Design)

Engineered for maximum power, reliability, and efficiency, the CSF High-Performance Charge Coolers (CSF #8178) deliver a groundbreaking upgrade for the BMW F90 M5 and F92 M8. Developed with CSF’s long-standing R&D partners, this system represents the world’s first and industry-exclusive high-performance cast end-tank charge cooler solution for the F9X platform.

As a global leader in BMW air-to-water charge-air cooling, CSF brings decades of innovation to this advanced cooling system. Drawing expertise from its renowned S55 one-piece charge cooler and its world-first F1X M5/M6 charge-air system, CSF integrates proprietary manufacturing technology and CFD-analyzed engineering to achieve unmatched performance.

Perfect Fitment, Maximum Cooling

Designed over the course of a year with multiple prototype revisions, the CSF Charge Cooler Set offers a true plug-and-play installation requiring zero modifications. Each unit fits precisely in the extremely tight F9X engine bay, utilizing every millimeter of available space for optimal airflow and cooling surface area.

Upgraded Construction for Superior Reliability

The OEM’s weak crimped-on plastic end tanks are fully replaced by CSF’s 100% TIG-welded, CFD-engineered cast aluminum end tanks. Unlike factory glued-on plastic charge pipes, CSF integrates one-piece seamless air inlet end tanks with built-in charge pipes for a stronger, more efficient design.

Each cooler includes dual 1/8” NPT methanol/E85 injection ports, strategically positioned directly in the post-intercooled airflow for maximum charge-air atomization and performance gains.

Track-Tested on the World’s Fastest F90 M5 Builds

Before hitting the market, CSF validated this system on two of the world’s fastest F90 M5 sedans. One Stage 3 test vehicle—producing ~900+ WHP / 1,000+ HP—showed a dramatic improvement in consistency and intake air temperature control, and reduced its 60–130 mph acceleration time by approximately 0.30 seconds after installing the CSF coolers.
