The air filter in the Chevrolet Cobalt prevents debris from getting into the engine air intake system. Chevrolet recommends inspecting the air filter every time the oil is changed or other maintenance is performed and replacing if it is clogged or excessively dirty. The filter should be replaced at least every 50,000 miles. Chevrolet does not recommend cleaning the air filter with compressed air, as this could damage it. A clean air filter improves air flow to the engine and increases engine performance.
