Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminium, media blasted, black anodised, and laser etched for a high-quality surface finish. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. The fuel rail is equipped with features to accept the OEM fuel injector clips.

This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM insulating spacers (Honda P/N: 16638-PNA-000) are reused and phenolic washers are included to thermally insulate the fuel rail from the aluminium intake manifold.
This fuel rail is compatible with all OEM Honda K-series intake manifolds (RBC, RBB, RRC, PRB, etc). If using an aftermarket manifold (Skunk2, etc) check with the manufacturer about fuel rail compatibility. If the manifold fits the OEM fuel rail, then the Radium fuel rail will also fit.
This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
This part only includes the fuel rail and the mounting hardware making it ideal for custom fuel plumbing applications. If using the stock fuel feed line, select the plumbing kit.
