Product Description

The K&N 33-2497 is a direct-fit, high-flow replacement air filter for the 2014-2017 Buick Regal 2.0L I4, 2014-2019 Chevrolet Impala 2.5L I4, and 2013-2016 Chevrolet Malibu 2.5L I4. It installs directly into the factory airbox in minutes with no cutting, drilling, or hardware changes. The multi-layer oiled cotton gauze construction delivers significantly greater airflow than a standard paper element while maintaining effective filtration to protect the engine from contaminants.

Designed to be cleaned and re-oiled every 75,000 miles rather than replaced, the 33-2497 is a cost-effective, long-term upgrade compatible with factory MAF sensors and engine management systems. It is emissions legal in all 50 U.S. states, will not void the manufacturer's warranty, and is backed by K&N's Million-Mile Limited Warranty. Note: this filter fits the 2.5L I4 Impala only - owners with the 3.6L V6 Impala should use K&N 33-2483 instead.
