Radium: NISSAN INJECTOR SEAT 25MM
These are the same machined aluminum injector seats used in Radium fuel rail kits. They are required when converting an OEM side feed injector to a top feed injector that uses a 14mm lower O-ring. They simply 'pop' into the intake manifold (1 required per injector). They seal to the machined injector counterbore using the included FKM O-ring.
NOTE: Because they are compatible with different cylinder engines, the injector seats are sold individually (not a set). Change quantity accordingly.
