The K&N 33-2496 is a washable, reusable panel air filter built on K&N's oiled cotton gauze high-flow design. The manufacturer says its layered oiled cotton media is engineered to improve airflow while capturing contaminants, and to increase horsepower. It measures 12.313 in L x 10.313 in W x 1.188 in H, and the manufacturer rates it up to 99% efficient.
Over a stock paper filter, the advantage is reuse. You clean and re-oil this element instead of replacing it, and the manufacturer lists a No-Hassle Lifetime Limited warranty and a 2.2 oz re-oiling amount. The trade-off is maintenance: a K&N needs regular cleaning and re-oiling, so buyers who skip that step lose the airflow and filtration benefit. This is a good fit for owners who want a long-term, drop-in intake upgrade for a 2013 to 2017 Cadillac ATS V6 (3.6L) and similar searches like K&N 33-2496 Cadillac ATS air filter, reusable cotton gauze panel filter, and drop-in performance air filter for ATS. For installation, the filter sits in the factory airbox, so the job is mostly opening the box, cleaning the sealing surfaces, and reseating the lid carefully.
The manufacturer's product page lists the 33-2496 for the 2013–2017 Cadillac ATS V6-3.6L F/I. The manufacturer's ATS application page lists this part number under several ATS engine sizes, which does not match the product page, so confirm your engine size and model year with the manufacturer before ordering.

This is a drop-in filter, so no cutting or modification is involved. Per the manufacturer's general K&N install guidance, clean the airbox and sealing surfaces of dust and debris, then seat the filter fully. Some K&N filters are meant to be set into the airbox lid first, so check the orientation before closing. The manufacturer notes that the clips need more pressure than with an OEM foam seal, so if the lid will not seat or the box flexes noticeably, stop and recheck the fit, because forcing it can crack the airbox. Owners on user forums commonly report that the airbox lid is the tricky part of the job.
