aFe Air Filter Power ProGuard OE 20-25 GM Sierra 3500 HD

aFe 20-25 GM Sierra 3500 HD Power ProGuard OE Replacement Air Filter provides engine air filtration for the GM Sierra 3500 HD platform while reducing wear by preventing harmful particles from reaching internal components.

This Power ProGuard OE replacement filter combines a deeply pleated, high-quality filter media with an added foam pre-filter to deliver durable protection and consistent service life for OEM-style intake systems.

• Deeply pleated, high-quality filter media — increases usable filter surface area to trap fine particulates, helping prevent abrasive contaminants from entering the engine and reducing component wear.
• Foam pre-filter — captures larger particles before they reach the primary media, preserving filter capacity and reducing the frequency of media loading under dusty conditions.
• OE replacement form factor — engineered to match original equipment fit and sealing characteristics for straightforward installation into the stock airbox without modification.
• aFe brand engineering — manufactured to aFe’s Power ProGuard standards for consistent filtration performance in heavy-duty applications.

Designed with serviceability and reliability in mind, this replacement element supports routine maintenance schedules and helps maintain intake system integrity over the filter’s service interval.
