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
- 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
