    Pull cleaner airflow into your BMW with the AFE POWER air filter 31-10270, a washable Magnum FLOW panel filter built with aFe's Pro DRY S synthetic dry media. It's an OE-replacement engine air filter that fits many BMW models, among them the 2017-2020 BMW 440i 3.0L, 2017-2020 BMW 440i Gran Coupe 3.0L and 2017-2020 BMW 440i xDrive 3.0L, with the rest listed in the "Vehicles it fits" section.

    • Pro DRY S synthetic media: three layers of progressive synthetic dry media, non-oiled, with tall, evenly spaced open pleats for strong dust-holding capacity and longer intervals between cleanings.
    • 100% polyurethane frame: a boxed polyurethane frame built for extra-long service life.
    • Washable and reusable: cleaned and reused across multiple cleaning cycles instead of tossed like a paper element.
    • Integrated urethane bump seal: a progressive bump-seal design for a tight, no-leak fit in the airbox.

    This AFE POWER intake filter is a black/grey panel filter engineered to flow more air than a stock paper element, helping maintain proper airflow to the engine. Country of origin: United States.
