2003 WRX/Apexi Thoughts 1 year ago

The quality of this filter is superb. The frame around it is solid and completes itself with the rubber gasket surrounding the top to ensure that the filter box is sealed. It's a little more expensive than a cheap filter from Autozone when factoring in the shipping. But, would I buy it again? Definitely! I mean, who wouldn't want more JDM in their Subaru? I did notice slightly better throttle response, but that's more likely due to changing out the dirty filter. There isn't any noticeable increase in power since it's just a drop-in filter. The included date/mileage record sticker is a nice touch so you can keep track of when to change the filter again.

I don't write many reviews but this is a good product. I've had three of these filters and not one problem. Better flow than OEM without sacrificing in filtration quality. It's a great little upgrade for those who want to keep their stock airbox.

QUESTIONS & ANSWERS

  • Q: Apexi filter  Fab4 months ago

    Will this fit my 2002 Impreza RS?
  • Q: Lifespan?   Cole Matthews5 years ago

    Just installed it tonight on my 2002 WRX sedan. Fits perfectly and has worked great so far. I live in south Florida and it is my daily driver. How many miles can I expect out of this filter? No auto-x or track or anything, just some spirited driving here and there :) thanks. I presume around 4k?
  • Q: Will this filter work on my car?  hhhp7 years ago

    Hi i have a 2007 subaru impreza 2.5i and i want to replace its stock air filter. In the owner's manual it says that the stock filter has oil on it so given that this Apexi is a dry filter i was wondering if it will not cause any unwanted effects on the air sensor or the intake system. Thank you
    • 0 of 0 people found the following answer helpful

      A:  Great question! The reason the stock filter has an oil on it is because it is a wet designed filter. This one is a dry, as you stated. We have many many customers running this filter with zero downsides! There is no unwanted effects on the air sensor.
