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.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!
