The Vital Leak-Prevention Kit for Side-Feed EJ Engines.
For the GC8, SF5, and early Liberty, the injector seals are a high-fatigue component. Every time the fuel rails are disturbed—or simply due to decades of heat-soak—these seals lose their ability to compress. Reusing old, flattened seals is the most common cause of "unexplained" lean conditions and fuel odors in the cabin.
The Genuine Subaru Injector Seal set is the 100% factory-spec solution. We provide these as a Set of Four to ensure that your entire fuel rail is refreshed simultaneously, eliminating the risk of a single old seal failing a week after you've finished your service.
Why the Roo Racing Seal Set?
-
Pliable Protection: Sourced fresh from Subaru Japan, these seals have the correct elastomeric properties to expand and seal perfectly against the manifold casting.
-
Tuning Integrity: A leaking injector seal is essentially a "phantom" vacuum leak. By ensuring a perfect seal, you allow your ECU to accurately calculate airflow, resulting in smoother idling and consistent AFRs.
-
Professional Grade: We don’t deal in generic "universal" O-rings. These are the specific Upper/Lower interface seals (OEM 16608AA020) designed for the unique geometry of the early Subaru fuel rail.
