    • Surprising "upgrade" for my 2024 Subaru Impreza RS!
With all the smoke in Southern California I figured it wouldn't be a bad idea to swap out my intake filter. Decided on this one since it has high mileage and is reusable. I really didn't expect this filter to be noticable other than on the wallet in the long run. The higher flow design doesn't add horsepower to the car but it definitely gives the illusion of it because my engine is MUCH more responsive to the gas pedal and it feels like it opens up with much more ease. Quality is about 100x nicer than the stock OEM Subaru filter which is pretty much just some paper origami in the shape of a filter. Installation was about as easy as possible (at least on my Impreza). Pop the hood and unclip the intake box, remove the old filter, put the new filter in, close the box and clip it shut. Done. Great upgrade and worth the extra price without question considering you can wash it and reuse it not to mention the miles you can go before you even have to think about it. Highly recommend it! There is a reason it gets such great reviews! ... show more

    • Ditch the oem and get this
It was a perfect fit, and the quality exceeds that of the manufacturer’s replacement filter (OEM). Sound quality remained unchanged, with no added noise from airflow, and overall airflow was not affected. In fact, the filtration is noticeably better—you can tell the difference immediately.

    • Great Product
I bought this K&N engine air filter for my 2025 Subaru Outback Wilderness 2.4L Turbo two days ago and it came quickly. The air filter is as advertised, and it's a great addition to my Subaru! The car seems to run smoother and have better power from a stop. I'm gonna love it. For those of you that think that an after market filter is a gimik, it's not. I've used K&N filters since 2004 and they've never disappointed! ... show more

Awesome life long filter. Once a year cleaning and it lasts as long as the car. High quality and filters out debris and dust.

    • K&N
I always use k&n on my vehicles. Never had any issues. After removing the carbon filter and installing this, I was able to gain 8 horsepower and a quicker throttle response. No intake noise though. Nothing significant but every little bit helps. Took maybe 5 minutes to install.
