08 STI Fittment Issue
john.boreham73302 2 years ago
I have fitted these to my 08 STI hatch. I had a fitment problem with these fuel rails. The rails did not sandwich down firmly on the injectors, in fact there was about 1/4 inch gap which allowed the injetcors to move aorund loosly between the inlet manifold and the fuel rail. I had to modify the mounting bracket on the fuel rail to re-position it closer to the inlet manifold to ensure the injetors were pushed firmly into both the inlet manifold and the fuel rail. It was easy to modify but a PITA and not what I expected. On a positive note my car is running noticeably better (i.e. eliminated stumble at low RPM) in combination with the Aeromotive pressure regulator I fitted at the same time. Certainly a big improvement on the OE rails and regulator. Next step is fitting the GTX3576.

Great Product and company. Much better setup than stock. Coupled with a new F.P.R. makes a great upgrade. Ensures equal fuel gets to all cylinders.


  • AnswerQ: Fuel Rail Setup  2002BugeyeWrx 2 years ago

    Is this fuel rail a parallel feed setup, or a series feed like stock one?

    • A: These are just rails without the lines. So you can set it up however you wish, either in series or parallel.

  • AnswerQ: OEM FIT AND INSTALL  jacob-compton26340 2 years ago

    will i need any additional parts? or are these a direct bolt in?

    • A: These will be a direct bolt on and replacement of the stock Fuel rails to the stock intake manifold, however the feed and return lines will be sold separately and are not included with these fuel rails and brackets.

  • AnswerQ: Advantages   Boost_gets_you_laid 2 years ago

    Is there really an advantage from a side mount or a top mount fuel rails

    • A: The largest injector size you can go with on a side feed system will be around an 850cc where with a top feed injector they go up to 2000CC and up. Other than that I wouldn't say there is an advantage to running one over the other.

  • AnswerQ: Fitment on a 2013 STI  bbrock17184345 2 years ago

    Hi, I just ordered these rails. They haven't gotten here yet but I pulled my OEM ones already and they look quite a bit different, which worries me. The OEM ones have hard fuel lines welded onto them, whereas the Aeromotive rails depicted do not. I'm just wondering if there are any other parts or anything special I need to do to make this work. My build is kind of on a timeline, and I don't want any surprises. Thanks!

    • A: These fuel rails are not compatible with the stock fuel lines and you will need custom fuel hoses with -8 AN ORB (O-Ring Boss) fittings to install these. You can find those fittings and lines at a local hose specialty shop.

  • AnswerQ: Compatibility with 2008 STI (JDM SPEC_ EJ20)  Mischievous M 3 years ago

    Based on the questions below, just curious if this kit will work with the JDM Spec STI. Reason I'm asking is because I've also just received my GREDDY Fuel Upgrade kit and am keen on upgrading the rails if this is compatible. If its compatible, are there other bits that I need to include to cater the Greddy injectors?

    • A: We have not done any in house testing with this set up using Greddy's Fuel Upgrade kit. So we are not able to confirm fitment.
