Product Description

The K&N 33-5049 is a direct-fit high-flow replacement air filter engineered for a wide range of GM vehicles sharing common airbox architecture, including the 2016-2025 Chevrolet Malibu, 2017-2019 Buick LaCrosse, 2018-2020 Buick Regal Sportback and TourX, and the 2019-2025 Cadillac XT4. It replaces the factory paper filter with a layered oiled cotton gauze element that flows significantly more air, supporting improved throttle response and engine efficiency across both the 1.5L and 2.0L turbocharged four-cylinder applications.

Installation is a straightforward drop-in swap into the existing factory airbox - no cutting, drilling, or adapters required. Unlike disposable filters, the 33-5049 is fully washable and reusable using K&N's Recharger cleaning kit, making it a permanent, cost-effective performance upgrade backed by K&N's 10-Year/Million Mile Limited Warranty.
