Radium Fuel Rail - Honda B-Series

Radium Fuel Rail - Honda B-Series

Application: Honda DOHC B-Series engines
Part Type: Billet aluminium upgrade fuel rail
Part Number: 20-0370-02

The Radium Fuel Rail for DOHC Honda B-Series engines is a high-flow replacement for the factory rail, with a large internal bore to support high power requirements. It is CNC-machined from 6061 aluminium, anodised and laser etched.

The 11mm ID injector bores accept factory injectors or equivalent aftermarket injectors, and the rail is ported for 8AN ORB and 1/8" NPT fittings. This is the rail only – fittings are sold separately, or add Radium's B/D/F/H-Series plumbing kit for a plug-and-play installation with the factory or an aftermarket regulator.
