Product Description

The K&N 33-2496 is a direct-fit, high-flow replacement air filter for select 2013-2024 Cadillac ATS and CTS models, as well as 2016-2024 Chevrolet Camaro equipped with the 2.0L I4 or 3.6L V6 engines. All three vehicles share GM's Alpha platform, and this filter is engineered to drop directly into the factory airbox with no cutting, drilling, or hardware changes. The multi-layer oiled cotton gauze construction flows significantly more air than a standard paper element while maintaining filtration protection for the engine.

Unlike disposable filters that need frequent replacement, the 33-2496 is designed to be cleaned and re-oiled every 75,000 miles, making it a one-time investment for the life of the vehicle. It is emissions legal in all 50 states, compatible with factory MAF sensors and engine management, and will not void the manufacturer's warranty. Note: this filter does not fit the Camaro SS, LT1, or ZL1 - those V8-powered trims use a different airbox and require a separate K&N filter.
