Franklin Engineering Limited is proud to supply CNC Machined adaptors to fit top feed style injectors to RB25DE and RB25DET intake manifolds.
Replacement of the standard side feed injectors with top feed injectors is common practice as top feed injectors are available in a wider variety of flow rates and are considerably cheaper.
With these injector adaptors, the standard RB25 injector seals are used along with the top feed injector bottom seals. Both are available new from Nissan.
An aftermarket top feed fuel rail, or standard RB20 top feed fuel rail can and will need to be used with these adaptors.
