Description
Radium Fuel Rails, VW/Audi/Bentley 6.0L W12
Application: VW / Audi / Bentley 6.0L W12
Part Type: Billet aluminium fuel rails (pair)
Part Number: 20-0876
The Radium 20-0876 billet aluminium fuel rails suit the VW, Audi and Bentley 6.0L W12. Each rail is machined with dual 3/8in (6AN) internal bores that connect internally to all injectors – combined, the two bores are 12% larger than a single 1/2in (8AN) bore – supporting all necessary engine power requirements, and the rails are compatible with all alternative fuels.
The O-ring sealed billet end cap ports are tapped 3/4in-16, compatible with 8AN ORB fittings, with a single port at each end of each rail.
Key Features
- Dual 6AN Bores: Two 3/8in internal bores per rail, 12% larger combined than a single 8AN bore
- 8AN ORB End Caps: O-ring sealed billet end caps, ports tapped 3/4in-16
- Alternative Fuels: Compatible with all alternative fuels
- Anodised Finish: Lightweight aluminium, anodised for wear and corrosion resistance
- Easy Install: No special tools required
What's Included
- Billet 6.0L W12 fuel rails (x2)
- Preassembled O-ring sealed end caps (x4)
- M6x1mm stainless steel hardware (x6)
Optional Parts
- Radium Denso Injector Connector Adapter (17-0065) – sold individually – needed where injector connectors interfere with the lower intake manifold
Important Notes
- This is an upgrade rail: OEM or OEM-equivalent injectors must be used (same height and the same upper and lower O-ring diameters and styles). Radium does not make injector recommendations – ask your tuner about brand and flow rate, and the injector manufacturer for a dimensionally correct part number
- Radium 17-0065 Denso injector connector adapters may be required if the injectors interfere with the lower intake manifold – with OEM injectors Radium recommends 6, for the inner injectors (cylinders 2, 4, 6, 7, 9, 11)
- Fittings are not included – select 8AN ORB fittings to suit your application
- Leave enough space around the ports for accessories such as fuel pressure regulators, gauges and fuel pulse dampers – contact iilumolab for Radium's dimensional drawings to check clearance
- Installation instructions are available in the Instructions tab
