    Great product. 8 months ago

    Purchased for my 2017 Forester. Fitment was correct. I purchased for the quality and longevity of the filter, as its washable and rechargeable; I wasn't expecting any impact on performance. I can't imagine it increased horsepower much, but the throttle response felt a lot more linear and controllable than stock. Definitely worth the price if you are thinking about it.

    This air filter is great so far. Fit just fine, and installed in seconds. Grab yourself a cleaning kit while you're at it and you should be set for the life of the car.

    Rallysportdirect sent the filter quickly! This was an easy installation. The quality of this air filter is unmatched! Immediately after installing I noticed a smoother drive, boost in speed for the turbo on my 11 wrx! Would definitely recommend this air filter for any car!

    QUESTIONS & ANSWERS

    • Q: 2008 Subaru Impreza 2.5i   ididitagain28 days ago

      Would this fit in a regular 2008 Impreza 2.5i
    • Q: Do I need a tune for this???  kylchn3 months ago

      Do I need a tune for this? or just drop and go? :)
      • 0 of 0 people found the following answer helpful

        A:  A tune is generally not required for a drop in air filter, but technically speaking it would be beneficial.

    • Q: 2015 WRX: Just purchased Invidia N1...  WRX 2015 3 years ago

      Just purchased Invidia N1 from you guys. Do you see any benifits from this filter as my air flow from my cat back is 3 inches now? I'm also nervous due to the high amount of negative feedback on using any high performance drop in filters due to access dirt going to your motor as well as the oil issue. Thanks
      • 0 of 0 people found the following answer helpful

        A:  You will see a slight increase in power and response. The issue pertaining to dirt and oil entering the engine is largely overblown in my experience.

    • Q: 2014 WRX  draymond4 years ago

      Meaning is it required to have a tune? I see most people equip this without a tune, still under warranty.
