The Radium Top Feed Conversion Fuel Rails convert the factory side-feed fuel injector system to a top-feed configuration. This conversion facilitates the use of high-flow fuel injectors, which are sold separately. The fuel rail injector bores feature a 14mm ID. These fuel rails are manufactured with a large internal bore, enabling support for substantial engine power requirements. CNC machining from 6061 aluminum, black anodization, and laser engraving provide a high-quality surface finish and compatibility with all fuel types, including E85.
