Sti injectors in na fuel rails

[nicklmort]

Do they go into the na fuel rails like this with the rubber piece from the rails



Or like this, leave the plastic piece on top of the injector and remove the rubber piece

Wow, I thought the STI injectors went in the ej25d rails, and the ej20g/k's went in the n/a 2.2 rails.

Pull the pintle cap off.
Mike, sti injectors go into 25d rails as well. Thats what i have in mine. The difference is how the rail mounts to the intake manifold. On the ej20g manny, the 25d rails work, and on the 22t manny, you need the n/a 2.2l rails. Its all in how far apart the two "ears" that mount the rail to the manny are.

Did you test-fit either to see what felt better?

Gotcha, I should have asked you first, lol.

Yes i did, it seemed exactly the same either way. I put them in with the rubber piece and no pintle caps though.

^that's how I did mine.

I think the rubber piece and the plastic piece are there for the exact same purpose....

Pic of the 2 different style fuel rails - EJ22 NA on top (actually out of a '94 Impreza, I believe). There lined up just like they'd look installed on the Passenger /Right side of the engine:
