The K&N 33-5031 is a washable, reusable panel air filter for the 2.4L four-cylinder in the 2015-2016 Honda CR-V. The manufacturer describes it as designed for high airflow while keeping the filtration needed for long engine life, and it arrives pre-oiled to drop into the factory air box. Compared with a disposable paper element, it is meant to be cleaned and reused rather than replaced, which makes it a practical upgrade for owners who want a K&N-style drop-in filter without modifying the intake. It is a filter swap, not a full cold-air intake, so expect the change to be a gentle improvement rather than a dramatic power gain. Shoppers searching for a 2015 CR-V 2.4L drop-in K&N panel filter, a washable air filter for the 2016 CR-V 2.4L, or a reusable replacement for the stock airbox element will find this part a match.
Installation is a lid-off, hand-tool job. The manufacturer's general installation hints advise disconnecting the intake tube if it makes the airbox lid easier to maneuver, and noting that some K&N filters seat more easily when placed into the lid first. The filter must sit fully in the groove on the lid, and the lid must sit correctly on the base before the clips are fastened. Because a K&N filter is firmer than a foam-sealed paper element, the clips will take more pressure to close. Stop if the box bends noticeably rather than forcing the clips, since a cracked airbox will cost more than the filter itself.
The manufacturer lists this filter for the 2015-2016 Honda CR-V with the L4 2.4L fuel-injected engine. Confirm your engine size and VIN with the manufacturer before ordering, since this filter is not listed for the 1.5L turbo or the 2.0L engines.
The manufacturer describes this filter as pre-oiled and ready to drop into the factory air box, so it is intended to go in as-is for the first installation.
The manufacturer describes this filter as washable and reusable. Follow the manufacturer's care instructions for the cleaning method and when to re-oil.
Plan on a basic, hand-tool installation. Remove the airbox lid, pull out the stock paper element, wipe down the sealing surfaces so no debris falls into the intake, and seat the K&N filter in the base with its orientation matching the lid groove. If the lid is hard to seat, disconnecting the intake tube can give you more room to maneuver it. Re-fasten the clips without forcing them, and confirm the lid sits flush before you close everything up.
