The K&N VF2043 is a washable, reusable replacement for the factory cabin air filter in the Cadillac CTS 3.6L V6. It protects your vehicle's occupants, interior, and HVAC system from pollutants & odors. The manufacturer lists the media as non-woven synthetic, with a footprint of 10.375 x 9.25 x 0.969 inches, so it is sized for the stock housing. Over the life of the car, a reusable filter avoids the recurring cost of disposable filters, which the manufacturer says more than 200 million disposable air filters end up in landfills each year.
Choosing this over a cheaper disposable filter comes down to ownership cost and cabin air quality. The manufacturer claims increased airflow improves heating/cooling efficiency and says the media is treated to help capture odor-causing contaminants. It also carries a No-Hassle Lifetime Limited Warranty. Owners on user forums report that these cabin filters load up quickly, so a clean, free-flowing filter matters on a daily driver.

Per owners on user forums, the cabin filter on these CTS models sits in a housing reached from the passenger side under the hood, behind the cowl panel, and on some years through the glove box. Expect to release the tabs on the housing cover and slide the old filter out. Owners note the new filter must follow a plastic guide on the driver's side of the housing to seat correctly, and that it can be squeezed and angled in. Match the airflow arrow to the direction the air travels into the cabin. Owners also point out that 2015 CTS procedures differ from 2014 and earlier, so use the access steps for your specific year.
