Just dropped in this filter into a 2024 Subaru sport today & Yes you instantly notice. Definitely more responsive, definitely notice what feels more lively, smooth transition through gears & definitely added hurry in higher Rpms. I love it. Satisfied.

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!

K&N has never disappointed me. Exact fit. Easy to install. Adds a little extra milage per gallon.

This is my 4th K&N filter I have owned. When I get a new car I usually invest in a new filter. It’s such a great feeling to go to the mechanic for service and tell them not to worry about the filter because you have a K&N installed. Amazon helped me identify the correct model for my car, and it fit like a glove. This thing was the easiest to install. I removed the old filter and installed this one in less than 10 minutes.

Item specific for the subaru crosstrek 2023, better airflow from the factory filter (without airbox modification) it is best to clean or dust off the factory airbox as well. Great product. It will last for many tens of thousands of kms.

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.
