The K&N 33-2497 is a panel-style replacement engine air filter built on the brand's layered, oiled cotton gauze media. The manufacturer says that construction is meant to raise airflow while still capturing contaminants. Because the element is washable and reusable, you clean and re-oil it instead of replacing it, and K&N backs it with a No-Hassle Lifetime Limited Warranty. For a 2.5L Malibu owner searching for a lifetime K&N panel filter, that reuse is the main value over a disposable paper element.
The manufacturer lists this filter for the Chevrolet Malibu L4-2.5L fuel-injected engine for 2013 through 2016 model years, and it says the filter needs cleaning only about every 75,000 miles under normal highway driving. Fitment data elsewhere varies on model years and on whether the 2.0L engine is covered, so confirm your exact year and engine before ordering. The 11.25 x 9.875 x 1.25 inch footprint is the main dimensional check for a stock airbox swap.
Installation is a drop-in job: the manufacturer designs these filters to seat in the factory airbox, so you swap the filter and reassemble the housing. Make sure the filter sits in the lid's groove and that the lid is fully seated on the base before fastening the clips, because forcing a misaligned lid can crack the airbox. Expect the clips to need more pressure than with an OEM foam seal, and stop if the airbox begins to bend.
The manufacturer's listing for this part names only the Malibu L4-2.5L engine. Some fitment data includes 2.0L applications, but the manufacturer has not confirmed that, so verify with K&N before ordering a 2.0L vehicle.
No. The manufacturer designs this filter to drop into the stock airbox, so no modification is expected.
The manufacturer says the filter needs cleaning about every 75,000 miles under normal highway driving. Driving conditions outside that profile may call for more frequent checks.
Most owners can complete this as a basic drop-in swap: remove the factory filter, wipe out any dust in the housing, and seat the K&N in place. Based on K&N's general install guidance for its drop-in filters, which is the closest documentation found for this type of filter, the main gotcha is alignment. Confirm the filter is seated in the lid groove and the lid sits squarely on the base before fastening, since mismatched parts can break the airbox. K&N's guidance also notes the clips may need more force than an OEM foam seal. Confirm the exact airbox fastener type and any required tools for your Malibu before starting.
