CSF BMW G90 / G99 M5 High-Performance Charge-Air-Cooler Set

For serious BMW G90 / G99 M5 owners pushing performance, the factory charge‑air coolers (CACs) often limit how hard you can run. The CSF High‑Performance Charge‑Air Cooler Set fixes that. Engineered to reduce intake temperatures, increase airflow, and resist heat soak, this set delivers measurable gains in power, consistency, and throttle response—especially under heavy boost, demanding driving, or track use.

Built with high‑efficiency cores, rugged end tanks, and precision foil construction, this CSF CAC set ensures your M5’s twin‑turbo setup runs cooler and more reliably. Whether you're tuning for more boost, running upgrades, or just want to protect the hardware under extreme conditions, this cooler set is the upgrade your performance build needs.
