Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter for your 2021 Chevrolet Express helps you prioritize maintenance. The engine air filter safeguards the engine’s intake system, improving performance, fuel economy and protecting components from abrasive particles, while the cabin air filter maintains interior air quality for driver and passengers by trapping pollen, dust and odors.
