Product Description

The Radium Engineering 20-0748 is a 90-degree V2 quick connect fitting that adapts the 19mm female quick connect port on the valve cover to a 10AN male hose connection. Its 90-degree configuration is purpose-built for Gen 2 BMW B58TU engines (B58B30O1 and B58B30M1) - including the Toyota GR Supra A90/A91 and BMW Z4 M40i - which feature a vertical crankcase vent port that benefits from a right-angle exit to clear surrounding components. The fitting also installs directly on the Audi S6, S8, R8 (Type 42), and Lamborghini Gallardo valve covers that share the same 19mm V2 quick connect female port.

Internal O-rings allow the 10AN outlet to swivel even after installation, giving builders full flexibility to orient the hose in any direction for a clean, routed catch can installation. Machined from billet 6061 aluminum and Type-II anodized for corrosion protection, this fitting is a direct, tool-friendly upgrade over OEM rubber hose connections for builders running an air/oil separator or competition catch can.
