The Precision Raceworks S58 Port Injection Kit is the ideal solution for those running the CSF Radiators Charge Air Cooler Inlet Manifold on their BMW G8X M3/M4 or G87 M2. Specifically designed to work with CSF’s built-in fuel rail, this version of the kit does not include a fuel rail and instead includes all necessary fittings to connect directly to the low-pressure fuel supply—with no cutting, splicing, or custom fabrication required.
This kit is the perfect addition to your billet inlet manifold, eliminating the need to source AN fittings, fuel hose, and adapters individually. It features Precision Raceworks’ trusted, race-ready fuel connections for clean, reliable installation. Included in the kit is an AN8 Male ORB to AN6 Female ORB Adapter, simplifying the connection to the existing CSF rail.
Whether you're adding port injection for ethanol blends or building a high-boost setup, this is the cleanest and most efficient way to extend your fuelling system.
