    OEM quality
    BMW dealer wanted $300 to replace the cabin filters. Watched a 5 minute video and ordered these up. Look identical to OEM and easiest cabin filters I've installed. Save yourself a ton of money and install these yourself. BMW quality without the BMW price.

    Great price
    I love Mann filters. Great for the price and great quality. I was surprised how cheap they were ( my car takes 2 filters and two come in the box). They fit like a glove and now I am enjoying fresh air
