To replace the engine air filter in the 2020-Present Cadillac CT5, open the hood and locate the air filter housing on the driver's side.

Common issues with the 2.0L engine include rough idling, reduced power, or the check engine light illuminating. Start by scanning for trouble codes using an OBD-II scanner.

To optimize the performance of the 2.0L engine, ensure regular maintenance is performed, including proper oil changes and air filter replacements. Use high-quality fuel with an octane rating of 91 or higher for optimal performance. Avoid excessive idling and drive in a manner that allows the turbocharger to cool down properly. Consider upgrading to performance-oriented parts, such as a high-flow air intake or exhaust system, but ensure any modifications are done by a qualified technician to avoid voiding the warranty.
