Radium Subaru Injector Seat Kit, 4 Cylinder

These are the same billet injector seats used in Radium fuel rail kits for Subarus. They are required when converting an OEM side feed fuel rail to top feed. They simply ''pop'' into the injectors bores on the tumble generator valve housings. They seal to the machined injector counterbore using the included Viton O-ring.
