ACDelco GM Original Equipment A3141C (25945274) is a direct-fit engine air filter engineered to keep airborne dirt and debris out of your engine while preserving factory performance.

Designed to the exact specifications used in new GM vehicles, this ACDelco Original Equipment air filter replaces the factory unit with the same shape, media and sealing characteristics.

Installation is straightforward and intended to match the vehicle’s stock intake layout—verify fit with your VIN before purchase to ensure compatibility.

How does this filter protect my engine without reducing airflow?

The A3141C balances particle capture with controlled airflow using advanced filter media and optimized pleat geometry. That combination traps contaminants while allowing the intake system to draw enough air to preserve fuel-air mix and throttle response.

• Multi-layer filter media for high dust-holding capacity.
• Pleated design to increase surface area without restricting flow.
• Factory-matching dimensions and seal to prevent bypass.

How easy is installation and maintenance?
