BMW S63 Charge Air Cooler for F9X M5 M8

The Wagner Tuning high-performance S63 intercooler for BMW M5 & M8 (F9X) delivers a dramatic cooling upgrade with 75% more core volume compared to the factory unit. Designed for the 4.4-liter V8 biturbo engine (S63 B44T4), this intercooler increases charge air density, reduces intake temperatures, and helps the turbo system operate more efficiently—resulting in stronger power delivery and improved consistency under high load.

Engineered by Wagner Tuning with optimized CAD-modeled end tanks and CFD airflow simulation, the intercooler minimizes back pressure while maximizing cooling performance. The cast aluminum construction and heat-conductive anti-corrosion coating enhance durability and thermal efficiency, making it suitable for street performance and track use alike. Additional WMI ports support water-methanol injection setups, offering further tuning flexibility.

Installation is plug-and-play with included silicone hoses, mounting hardware, and detailed instructions. A parts certificate ensures full road legality in applicable regions, giving enthusiasts performance without regulatory compromise.
