RVNG G8X/S58 Upgraded Charge Cooler Manifold (G87 M2, G80 M3, G82 M4)

PLEASE ONLY BUY UNCOATED IF YOU PLAN TO POWERCOAT THE MANIFOLD YOURSELF AS ITS RAW ALUMINIUM AND CAST

The BMW S58 engine in the G8X platform is an evolution of BMW’s legendary inline-six lineage — but as power levels rise, the factory charge air cooler manifold becomes one of its biggest weaknesses. The OEM setup uses a crimped plastic plenum mated to a tube-and-fin intercooler core, which struggles to handle even mild increases in boost pressure. Many have seen failures at just a few PSI over stock.

The RVNG RaceWorks Charge Air Cooler Manifold eliminates these limitations entirely. Engineered from cast aluminum with a fully TIG-welded bar-and-plate core, this manifold is built to withstand extreme boost pressures and heat cycles—making it ideal for both high-performance street builds and full track applications.

Every internal surface was CFD-optimized to ensure balanced flow across all six cylinders, eliminating hot spots and ensuring consistent fueling under load. The result is a system that not only increases cooling efficiency but also enhances throttle response and airflow uniformity—critical for high-horsepower S58 setups.

Whether paired with stock twins or a full single turbo conversion, the RVNG manifold delivers unmatched reliability, flow, and performance headroom for the S58 platform.
