ACDelco engine air filter A3245C (84498926) — GM OE fit, high-efficiency pleated media

ACDelco GM Original Equipment A3245C (84498926) is a factory-style engine air filter engineered to trap airborne particles and protect your GM engine while preserving factory fit and airflow.

This ACDelco GM Original Equipment air filter is manufactured to the specifications validated by General Motors for use in Chevrolet, Buick, GMC, and Cadillac vehicles. It combines a high-efficiency media, a durable frame, and precision sealing surfaces so airborne dirt and debris are kept out of the combustion chamber without compromising engine breathing. The A3245C (84498926) replaces or matches OE performance and is backed by the same engineering standards used during vehicle production.

How does this ACDelco air filter protect the engine?

The filter uses a dense filter media and a secure perimeter seal to prevent unfiltered air from bypassing into the intake. By capturing contaminants before they reach the engine, it helps maintain combustion chamber cleanliness and reduce wear on internal parts. It does not alter engine tuning or airflow characteristics compared with OE parts.

• High-efficiency pleated media captures dust, pollen, and road particles
• Rigid frame maintains shape under intake vacuum and heat
• Tight sealing lip reduces bypass risk and ensures proper airflow routing

Will the A3245C fit my GM vehicle and install easily?

This part is designed to match GM original equipment dimensions and mounting features for a direct replacement. It installs using the factory airbox and clamps without any modification. Always verify cross-reference numbers or vehicle compatibility before purchase to ensure a precise fit.

• OE-style form factor for drop-in replacement in compatible airboxes
• Direct-fit seals and flange geometry match factory mounting points
• No trimming or adapters required when matched to the correct vehicle application

How often should I change the ACDelco air filter and what affects its life?

Replacement interval depends on driving conditions: mileage, dust exposure, and local climate. Under normal highway and city driving, many drivers replace their air filter every 12,000–30,000 miles, while dusty or off-road use may require more frequent changes. Inspect the filter during routine service and follow your vehicle’s maintenance schedule.

• Inspect at each oil change for heavy contamination or damage
• Shorten interval if driving on unpaved roads, in desert climates, or behind construction
• Replace earlier if filter media appears clogged or airflow is restricted

What are the material and quality features that set this OE filter apart?

The ACDelco GM Original Equipment label indicates the filter meets GM’s engineering validation and production standards. It uses filtration media chosen to balance particle capture with airflow, plus a frame and seal designed to withstand under-hood temperatures and vibration. Some parts under this program were previously sold as GM Genuine Parts (OE) or ACDelco Professional, reflecting continuity in quality.

• Media selected for high filter capacity and consistent efficiency
• Durable frame preserves filter geometry through service life
• Manufacturing and validation by GM engineers for compatibility and performance

Who is this for: The ACDelco A3245C (84498926) air filter is intended for owners and technicians who want a direct replacement that matches factory specifications for Chevrolet, Buick, GMC, or Cadillac models. Choose this filter if you prioritize OE fit, reliable particle capture, and a tight seal that helps keep unfiltered air out of the engine. It’s a practical option for routine maintenance, service shops, and DIYers seeking a trusted GM-backed part.
