High-Flow Original Lifetime Engine Air Filter: Washable, 33-5064

I was having great pains finding filters that fit my Subi, It seems the STI that are listed aren't actually compatible with gen5 of the imprezas and after returning more than I would like to admit I was about to give up when I went to K&N's site as saw their product listed compatibility ONLY for gen5... So I bit the bullet and bought the most expensive filter yet. It was worth every penny. The Filter fit perfectly and installation took under a minute, the filter was pre-oiled (something I haven't seen any reviews mention) and improved my MPG from an average of 33 back up to 40 like the day I bought the car... and then a few extra to 44mpg. needless to say your mileage may vary (pun intended) but I am completely happy with the filter so far. It will take a while before I know if the performance will stay that high and save me more than the cost of the filter in gas costs over the life of the car but for now I can at least stop going to the dealer every time I need a new filter. TL;DR Fits, works as good or better than OEM, highly recommended. If anything unexpected happens I will update my review.

Fits 2026 Subaru wrx and works great.

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!

Due to living in California where aftermarket performance parts are incredibly limited, it's great to know I can at least replace my stock filter with a drop in. Although it doesn't give the throaty sound of a cold-air intake, whether it's placebo or genuine performance I do feel the acceleration curve is ever so slightly smoother. There is a tiny bit of a more audible improvement in the sound quality but it's quite subtle. Fuel economy has gone up a marginal amount as well.

Performance is definitely enhanced. There is a negligible increase in gas mileage, but not having to replace the air filter and only having to clean it a couple of times a year is a big plus. I have used K&N filters on all my cars for the past 20 years.

Works perfect. Will increase The engine performance easy to clean, worth every penny. They are the only filters I use in my vehicles

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!

It dropped right in, and seems to be working just fine. Only time will tell if the filter will lasts as advertised. The one in my motorcycle does. So I feel confident, it will also.

Good product, very fast delivery, fit perfectly on original filter box. Strongly recommended

まだ交換後200km程度しか走行していないので詳細の燃費状況は不明だが、アクセルレスポンスは以前より良くなっている気がする。

SUBIO DOS PUNTOS LA COMPUTADORA DE VIAJE, ES PRACTICO, COMPRE SUS LÍQUIDOS ORIGINALES LIMPIADORES. NO QUITEN EN FILTRO DE CARBON ACTIVADO MONTADO PREVIO AL FILTRO, NO ES RECOMENDABLE, QUITARLO AUMENTA LA CANTIDAD DE SEDIMENTOS EN EL AIRE SOBRE LA ADMISION. LA AGENCIA SUBARU ME DIJO QUE ES BUEN FILTRO, SOLO HAY QUE LIMPIARLO ANTES Y NO A LO RECOMENDABLE QIE DICE EL EMPAQUE, TODO DEPENDE DE LA CIUDAD DONDE VIVAS...SEGUN LA CONTAMINACIÓN DEL AMBIENTE. NO ES RADICAL EL AHORRO O EL AUMENTO DE POTENCIA COMO SE DEDUCE. ES MINIMO, PERO SI SIENTO UN POCO MAS LIGERO EL ACELERAR...A MI AUTO LE ENCANTÓ.

Great product could feel slightly more throttle response and performance.

Este filtro es un poco más grande y no encaja lo devuelves y tienes que pagar gastos de envio el código en kyn para este coche es el 33-2304
