These are the same machined aluminum injector seats used in Radium fuel rail kits for Subarus. 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 OEM side feed injectors bores on the intake manifold or TGV housings. They seal to the machined injector counterbore using the included FKM O-ring.
The 26mm injectors seats are for early Subaru EJ engines as well as the SVX EG33.
They are black anodized, as shown below.
The 22mm injector seats are for later Subaru engines. They are green anodized, as shown below.
Measure before ordering.
Both injector seat styles use the following lower injector O-ring measurements shown above.
