Radium Engineering's top feed fuel rail conversion kit replaces the factory side feed rails on 2004 to 2006 EJ255 and EJ257 engines so universal top feed injectors can be run. Each black anodized rail has three 8AN ORB ports (six total), with green anodized 22mm injector seats for 14mm lower O-rings and 15mm press-in thermal insulating spacers. Injectors are not included and must use 14mm top and bottom O-rings at 34mm height, such as Injector Dynamics ID1050, ID1300, ID1700, or ID2600 XDS in 34.14.14 form. Standard WRX top feed injectors do not fit.
