Radium Fuel Rail - Honda K Series

Application: Honda K-series with OEM (or OEM-compatible) intake manifolds – excludes K20C1
Part Type: Upgrade fuel rail
Part Number: 20-0230-02

Manufactured with a large 0.69in (17.5mm) internal bore, this Radium fuel rail can support all necessary engine power requirements for Honda K-series engines. It is CNC machined from extruded 6063 aluminium, media blasted, black anodised and laser etched.

Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors can be used, and the rail has mounting features for the OEM injector clips.

Important Notes

• Not compatible with the direct-injected K20C1
• Aftermarket intake manifolds (e.g. Skunk2) – confirm with the manifold manufacturer; if it accepts the OEM fuel rail, the Radium rail should also fit
• This is an upgrade rail, not a top feed conversion – OEM or OEM-equivalent injectors must be used (matching OEM injector height and upper/lower O-ring diameters and styles)
• Radium does not make injector recommendations – consult your tuner for brand and flow rate, and the injector manufacturer for a dimensionally correct part number
• Fittings are not included – select fittings to suit your application and allow space around the ports for regulators, gauges and pulse dampers
• Installation instructions are available in the Instructions tab

Vehicle Fitment

• Honda K-series engines with OEM intake manifolds (e.g. RBC, RBB, RRC, PRB)
• Aftermarket K-series manifolds that accept the OEM fuel rail
• Excludes direct-injected K20C1
