Radium Engineering Fuel Rails – Nissan 350Z (07–09), 370Z / VQ-Series

These Radium Engineering fuel rails are designed for the Nissan VQ35DE, VQ35HR, and VQ37VHR engines. Machined from 6061 aluminium and black anodised for compatibility with all fuel types including E85, they feature a large internal bore to support high horsepower applications.

Each rail includes four 8AN ORB ports (two ends, two bottom), offering flexibility for plumbing configurations—parallel, series, or return systems. The 14mm injector bores are compatible with OEM injectors as well as aftermarket injectors that share the OEM VQ fitment.

The rails mount using stainless steel brackets and hardware, and the OEM injector clips can be reused for VQ35DE and VQ35HR applications.

Note: For VQ35DE applications, due to intake manifold mounting boss clearance, two Radium 14-0150 8AN ORB plugs must be installed in one of the centre ports on each rail.

• Nissan 350Z (VQ35DE / VQ35HR)

• Nissan 370Z (VQ37VHR)

• Infiniti G35 / G37 (VQ35DE / VQ35HR / VQ37VHR)

• Other Nissan VQ variants with similar intake manifold layout
