Radium Injector Seats, 22mm, Subaru Forester XT SG 03-05 / Liberty GT BL 04-06

Radium Injector Seats — 22mm, Subaru Forester XT SG (2003–2005) / Liberty GT BL (2004–2006)

These are the same machined aluminium injector seats used in many Radium Engineering fuel rails. Required when converting from OEM fuel injectors to aftermarket injectors, they press-fit directly into the intake manifold or TGV injector ports with no modifications required. Using the included FKM O-ring, they seal into the machined injector counterbore to prevent vacuum or boost leaks. The injector seat bores are designed for use with a common 14mm lower injector O-ring.

Please note: These injector seats are sold individually (singles). Most Subaru EJ engines require 4 seats — please order the quantity you need.
