RB25DET

The stock injectors are side feed, so these top feed injectors are set up to work with our RB25 top feed conversion fuel rail and adaptors as shown. For other applications, you may need different O-rings and rail adapter couplings.

We can offer plug and play harness adapters, or fresh plugs and pins to attach to your stock wiring loom
