Cosworth makes a quality product, again!
erizeWrX 16 days ago
I bought this Cosworth Drop-In filter for my 15 WRX, just because I needed to replace my old dirty stock one. This filter is well worth the money invested. The throttle now reacts more quickly and efficiently. The sound of the intake and turbo have slightly increased, and I’ve seemed to get slightly better gas mileage as well. All around, this filter is well worth the money!

I'm disappointed......
Themetalguy852 6 months ago
I'm disappointed that I couldn't be the first person to give this less than a five star review. This $48 dollar product is absolutely mind blowing. Throttle response is greatly improved and smoothed out, no more choppyness during normal driving situations in the lower rpm, and I could swear it's easier to rev match and shift in general. The sound of of the intake is definitely a little louder .... aka more awesome. And to top it off, for the first time basically ever on my MAP stage 1 tune I had ZERO.... ZzzzEeeRrrOooo -1.41 knock readings on my half hour test drive. I just feel in love with my wrex all over again. Seriously, my mind is blown that such a simple, stupid sounding"upgrade" could make as much of a difference as it did. Well exceeded my expectations. Buy it.... now.....

Awesome value for the money!
zbuckley22b13960 11 months ago
I was on RallySports website looking for parts for my newly acquired 2017 WRX, and as I was about ready to check out I noticed this Cosworth air filter had a ton of 5 star ratings. I thought it seemed a little odd for such a basic item, but all the reviews said it was well worth it, so I said what the heck, may as well. After receiving the package I installed the air filter on my new WRX with only 602 mils on it, still breaking it in. I was very surprised to find that even while keeping it below the 3000rpm limit during the break in process, the benefits of the filter were very noticeable. The car runs and drives much smoother, and the choppyness at part throttle lower rpm (normal driving) was mostly eliminated. 100% worth every penny, just buy it!

  • Q: Filter life  charlesbuck3989131 4 years ago

    Answer

    What is the mileage life of this Cosworth panel filter? Same as the OEM?


    • A: How long a filter will last depends heavily on the conditions and you can expect this to last a little longer than OEM.

  • Q: Tune?  Steelman87 4 years ago

    Answer

    Just Curious If A Tune Would Be Needed With This Drop In Filter?


    • A: We recommend tuning for any upgraded filters, especially on 2008+ models.

  • Q: This filter + Cobb AP  Mitch567 5 years ago

    Answer

    13 WRX I noticed that COBB released a new OTS tune for STI's that is specific to this panel filter. However, no new tune for WRX's. Would you recommend using this filter with the OTS stage 1 (stock airbox) tune?


    • A: With any panel filter I would recommend a stock airbox tune. It would not be to factory specs but it should not be off to the point of causing an issue.

  • Q: Freebie  dumschmuck 6 years ago

    Answer

    When I purchase this filter, will it come with a free Cosworth sticker? How many miles do you think this should last me before changing?


    • A: This filter does not include a Cosworth sticker. There are many variables to determine filter life, but this will definitely last longer than the OEM air filter.

  • Q: Maintenance   rallyjerry602932 7 years ago

    Answer

    Does Cosworth state how to clean this filter? I would assume soapy water, rinse, and air dry?


    • A: To retain optimal performance, we suggest replacing the filter with new. However the filter element is synthetic and can be washed with soap and warm water. Please ensure the filter is completely dry before reuse.
