    Why do I need a title?  9 months ago
    4out of 5stars

    Well if you've worked on a Subaru you know how big pain injectors and spark plugs are. However, the packaging was great, and as my srt4 buddy said, "damn those things are sexy" lol. Installed them over the weekend, have no input on how they hold up yet as I'm waiting on the tune still. I, however, would buy it again!

    Dont skimp on Injectors wrx 2014 1 year ago
    5out of 5stars

    I made the mistake of buying 850s from another c.o. They gave me misfires that could not be tuned out. I should have just bought these first time. Really nice on e85. No ticking noises. Good idle.

    Patience is a virtue 2 years ago
    5out of 5stars

    I needed to upgrade injector size so these were it. Injectors are great, however be patient during install if doing it yourself. Works great with my stock rails.

    Fantastic injectors  3 years ago
    5out of 5stars

    Paired these with a FP 16g turbo, TurboXS front mount, and about every other mod cobb has to offer on my 04 wrx and I am more than pleased. #Hippotuning was able to dial my car in perfect, idles a million times better and the power is there now when I want it. Plus RSD has the fastest delivery’s you could ask for

        A:  Just get these. Even though they are larger than you need for your power goals, they are a phenomenal injector that have a near stock spray pattern even at idle. Thanks

    • Q: Tune required?  Nex Brito7 months ago

      I have a to replace my fuel Injectors due to system too rich code. Can this be a direct install without tuning or will a tune be required?
      • 1 of 1 people found the following answer helpful

        A:  A tune would be 100% required, and if the rich condition has not been diagnosed yet, I would get to the bottom of that first. A stuck injector, while not impossible, is unlikely on these cars, and the rich code is most likely being caused from something else. Thanks!

        A:  i also had the P0171 System Too Rich code. If it is not your injectors, then it can very well be your turbo inlet, or even your MAF sensor. I cleaned my MAF Sensor and the code hasnt been back since
