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.
