So I needed a cabin air filter for my 2017 Santa Fe XL. Rock Auto had them for $3.16 cents each. Brand is "Ultra Power". I bought two. Shipping was $5.00 for both. The part number is not a sticker-but an image printed right on the package. Around the web WIX uses the same part number for their filter-for an average of $10.00 each. Looks identical. It pays to shop around.
