Radium Fuel Rail Kit - Audi R8 4S/Lamborghini Huracan 724 (V10)
Manufactured with very large .069" internal bores, the fuel rails can support all necessary engine power requirements. They are CNC machined from 6061 aluminum, anodized, and laser etched for a high quality surface finish. Each fuel rail has six 8AN ORB ports (12 in total). Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors, or any equivalent aftermarket injector, can be used. As shown below, the factory injector retaining clips can be reused.
20-0866 only includes the fuel rails and the mounting hardware, making it ideal for custom applications. Extra fittings, hoses and other fuel plumbing items will be needed to complete the installation. For custom applications that demand a fuel pressure regulator and/or fuel pulse damper, a good location is on the right rear ports, as shown.
The fuel rail is compatible with all fuel types including popular alcohol mixtures such as E85.
