Radium Subaru injector seats are the same machined aluminium seats used in many Radium fuel rails. They are needed when converting OEM side-feed injectors to aftermarket top-feed injectors.

The seats press-fit into the intake manifold or TGV injector ports with no modification and seal against the injector counterbore with the included FKM O-ring, preventing vacuum and boost leaks. The bores suit a common 14mm lower injector O-ring.

Key Features

• Two Sizes: 22mm for later EJ engines, 26mm for earlier EJ and EG33 engines
• Press-Fit Install: Fits the manifold/TGV injector ports without modification
• FKM O-Ring Seal: Prevents vacuum and boost leaks
• 14mm Lower Bore: Suits common aftermarket top-feed injectors
