Donaldson GM Factory Air Cleaner Box Filter Assembly is an OEM-grade replacement designed for Cadillac CTS models, manufactured by Donaldson to GM factory specifications. It combines the air cleaner box with the filtration element to manage intake air quality and protect the engine from dust and debris. Intended as a direct replacement for the Cadillac CTS factory air intake housing, it uses standard GM interfaces to ensure proper fit and seal within the factory system.
