    • Q: Intake  Shmurda 10 months ago

      Can I use just an access port for this intake?
      • 0 of 0 people found the following answer helpful

        A:  The Accessport will not come with a pre-installed map for this particular intake, however any decent tuner would be able to tune for this intake using the Cobb AccessPort. Thanks!

    • Q: CA legal?  dsh2 years ago

      Is this item CA legal? Seems some are and some aren't?
    • Q: AEM cold air intake  Austin2 years ago

      Do I need to use aftermarket tuning for this?
    • Q: Why is this not compatible with a 2016 STi?  SpeedHoles2 years ago

      What was physically changed that this will only fit 2018+ STi? I'm looking to purchase this for a 2016 STi since the design utilizes the factory scoop. But why is it not shown as compatible with 2015-2017? What changed?
