ACDelco air filter A3238C (23335811) OEM fit — multi-layer media and sealed edges

The ACDelco GM Original Equipment A3238C (23335811) air filter is a factory-validated replacement that traps airborne particles and provides the correct fit and seal for compatible GM vehicles.

Designed, engineered and validated by General Motors, the ACDelco GM Original Equipment A3238C (23335811) air filter replaces the factory-installed element with the same specifications used in production. It combines a high-capacity filter media with molded sealing surfaces so unfiltered air is minimized at the intake. That approach helps preserve engine breathability and maintains the airflow characteristics GM engineers intended for Chevrolet, Buick, GMC and Cadillac applications where this part number applies.

How does this air filter protect my engine during daily driving?

The A3238C element captures dust, pollen and other airborne debris before they reach the combustion chamber, reducing abrasive contaminants in the intake system. It uses multi-layer media tuned for balance between filtration efficiency and airflow to avoid starving the engine of air while still keeping particles out.

• Multi-layer filter media traps fine and coarse particulates
• Molded sealing edges reduce bypass risk around the housing
• Engineered to match GM factory airflow specifications
