The K&N E-0650 is a round, drop-in replacement for the factory engine air filter on the 2016 Cadillac ATS-V with the 3.6L V6 fuel-injected engine. Its cotton-gauze element is reusable and engineered to last for the entire lifespan of your vehicle, according to the manufacturer. Over time, that matters more than the sticker price: you buy one element instead of repeat paper filters, and the manufacturer backs it with a No-Hassle Lifetime Limited warranty. Be realistic about performance, though. The manufacturer promotes horsepower and throttle gains, but no specific output figure is confirmed here, and under 99% of throttle positions, your paper filter is capable of flowing more air than your engine can use, according to owners on user forums. Buy this filter for reusability and a clean, quality-oiled intake, not as a guaranteed power upgrade.
Looking for an ATS-V 3.6L drop-in K&N filter, a reusable E-0650 replacement, or a washable cotton-gauze ATS-V intake filter? This filter installs in the stock airbox, so no tuning or intake tube work is needed. The element measures 5.375 in (137 mm) tall with a 3 in (76 mm) inside diameter and a 4.875 in (124 mm) outside diameter. Owners on user forums describe the swap on a 2016 ATS-V as very simple, which makes it a practical weekend upgrade. Check the fitment notes below before ordering, because the application listing and package quantity differ between sources.
The manufacturer's product page lists the 2016-2019 Cadillac ATS-V V6-3.6L F/I, while its vehicle-specific page lists only the 2016 ATS-V 3.6L V6 gas application. Confirm your model year and airbox configuration with the manufacturer before ordering.
The manufacturer describes this element as washable and reusable and lists a re-oiling amount of 1.53 oz (45 ml). K&N's install documentation points to its Recharger service kit for cleaning and re-oiling, though that reference comes from a different part's instruction sheet, so confirm the correct kit for the E-0650 with the manufacturer.
Owners on user forums report that oil migrating from an oiled filter can coat the mass airflow sensor and throttle body. Those owners say over-saturating the element after cleaning is usually the cause, so apply oil sparingly and let the filter dry fully before reinstalling.
This is a drop-in filter, so the job centers on the stock airbox rather than the intake tube or engine management. Owners on user forums describe the swap on a 2016 ATS-V as straightforward. On later ATS-V airboxes, one owner found that the owner's manual calls for loosening six screws to access the filter, but two of them were hard to reach, and that owner had to remove the airbox to finish the job. Plan for basic hand tools and extra time if your airbox is mounted tightly. Before reinstalling, wipe out debris in the airbox and check the seal around the filter. Make sure the lid seats fully so unfiltered air cannot bypass the element.
