Description
The aFe POWER Magnum FLOW Pro GUARD7 Air Filter is engineered to deliver maximum airflow, superior filtration, and long service life for 2011–2016 Chevrolet Silverado HD and GMC Sierra HD trucks equipped with the 6.6L Duramax diesel engine.
This premium oiled OE-style replacement air filter is designed to outperform restrictive factory paper filters, providing up to 44% increased airflow for improved throttle response and overall engine efficiency. Its innovative inverted filter design fully utilizes the available space inside the factory air box, allowing for significantly more filter media than traditional drop-in filters.
The Pro GUARD7 filter features seven total filtration layers, including five layers of progressively finer cotton gauze media combined with two layers of synthetic media. This advanced construction delivers exceptional dust-holding capacity and maximum cumulative filtration efficiency, making it ideal for severe-duty and off-road environments where engine protection is critical.
Built for durability and long-term use, the filter is constructed with 100% polyurethane top and bottom caps and an integrated urethane bump seal that ensures a tight, leak-free seal over the life of the filter. The washable and reusable design allows for multiple cleaning cycles, extending service intervals while reducing maintenance costs.
Designed as a direct OE replacement, the aFe POWER Magnum FLOW Pro GUARD7 Air Filter installs easily into the factory air box with no modifications required, providing reliable performance and protection backed by aFe POWER’s engineering excellence.
