Review: 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.
Review: 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!
