Product Description

The Radium Engineering 20-0458 Fuel Rail Kit is engineered specifically for Nissan and Infiniti models powered by the VQ engine family - including VQ35DE, VQ35HR, and VQ37VHR platforms. Its large internal bore and precise 14 mm injector ports enable high fuel flow performance, supporting upgraded fuel injectors and E85 use.

CNC-machined from 6061 aluminum and finished with hard anodize, the rail provides strength and corrosion resistance. Each rail features four 8AN ORB ports for ease of integration with fuel pressure regulators, dampers, or sensors. OEM injector clips are reused for a seamless direct-fit installation on street and track builds.

Please note: this base kit includes only the fuel rails and mounting hardware. Plumbing kits (PN 20-0468 for VQ35DE, 20-0469 for VQ35HR/VQ37VHR) are required for full feed line compatibility. Plug kits (PN 14-0150) are needed for certain center ports on VQ35 engines. This kit is ideal for builders seeking reliable, high-flow fueling solutions on VQ-powered Z/Infiniti vehicles.
