The BMW S58 is the latest evolution of BMW's legendary inline-six, but as boost climbs the factory charge-air cooler manifold becomes one of its weakest links. The OEM unit crimps a plastic plenum to a tube-and-fin core that struggles with even mild boost increases — failures have been reported just a few PSI over stock. The RVNG RaceWorks Charge Air Cooler Manifold removes that ceiling entirely.

It's built from cast aluminum with a fully TIG-welded bar-and-plate core, engineered to take extreme boost and repeated heat cycles for both high-power street builds and full track use. Every internal surface is CFD-optimized for balanced flow across all six cylinders, killing hot spots and keeping fueling consistent under load — so you gain cooling efficiency, throttle response, and airflow uniformity at once. Whether you run stock twins or a full single-turbo conversion, it delivers the reliability and headroom an S58 needs.
