Description

For a properly planned performance build, the Radium Engineering Nissan VQ FPD Adapter (8AN ORB / 11mm Bore / 42mm Spacing / M6) reduces pressure pulsations created by injector opening and fuel-pump operation so pressure at the rail stays more stable. Smoother fuel pressure can improve consistency in high-flow EFI systems, particularly when injector events or rigid plumbing create noticeable pressure oscillation.

Radium specifies 8AN ORB AN/ORB sizing for this version, so confirm the surrounding system uses the same sizes and standards. Choose the correct pressure range and mounting thread. Radium specifies these dampers are not for the low-pressure side of mechanical direct-injection pumps.
