Radium - Injector Seats for Nissan Top Feed Conversion Fuel Rails

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.
