Radium Engineering 1UZ-FE Fuel Rails - Lexus LS400 / SC400 1990-1997 - Pair

These CNC machined rails replace the factory 1UZ-FE units with a 0.7 in inner bore that keeps supply even across all eight injectors at higher flow than stock. Each rail carries three 8AN ORB (3/4in-16) ports, so feed, return and an accessory such as a gauge or regulator can all be plumbed without stacking adapters on adapters. They are lightweight anodized aluminum, bolt directly to the engine with no permanent modification, reuse the factory thermal insulating spacers, and need no special tools. These are upgrade rails for OEM or OEM equivalent injectors rather than a conversion to a different injector body.
