The RVNG G8X/S58 Upgraded Charge Cooler Manifold from Rvng RaceWorks is engineered to eliminate one of the biggest limitations of the factory S58 cooling system. While the BMW S58 engine continues the legacy of BMW’s legendary inline-six platform, the OEM charge cooler manifold relies on a crimped plastic plenum and tube-and-fin intercooler core that can struggle with increased boost pressure and higher power levels.

Designed for enthusiasts demanding dependable performance cooling, the upgraded S58 charge cooler features a stronger, more efficient design that helps reduce heat soak, improve durability, and maintain consistent intake temperatures under demanding driving conditions. It’s the ideal solution for high-performance street and track builds seeking reliable cooling and long-term performance.

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.
