Overview

The AEM DryFlow Air Filter is a high-performance replacement air filter designed specifically for the Dodge Durango and Jeep Grand Cherokee equipped with 5.7L Hemi and 6.4L 392 engines from 2011 through 2026. Engineered to provide an optimal balance of airflow, filtration efficiency, and durability, this washable synthetic air filter is ideal for enthusiasts seeking to enhance their vehicle’s throttle response and horsepower without compromising engine protection.

Unlike traditional oiled filters, the DryFlow uses an innovative oil-free synthetic media that simplifies maintenance and eliminates the mess and hassle of oiling. This filter is reusable for the life of your vehicle, making it a cost-effective and environmentally friendly upgrade for daily drivers and performance enthusiasts alike.

The AEM DryFlow Air Filter combines advanced materials and design to deliver superior performance and protection. Key features include:

• Oil-free design eliminates the need for messy oiling and reduces maintenance time
• Captures up to 99% of harmful contaminants, protecting your engine from dust and debris

Construction & Design

The AEM DryFlow Air Filter features a non-woven synthetic filtration material that is engineered for maximum airflow and superior contaminant capture. The oil-free media is durable and resistant to wear, allowing for repeated cleanings without degradation in performance. The panel filter is precisely sized with dimensions of 9.625 inches in length, 8.875 inches in width, and 2.375 inches in height, ensuring a perfect fit in the factory air box.

Its robust construction withstands demanding driving conditions, including off-road and racing environments, while maintaining consistent filtration efficiency. The absence of oil also prevents filter media saturation and potential damage to sensitive mass airflow sensors.

Performance & Sound

By improving airflow to the engine, the AEM DryFlow Air Filter enhances throttle response and can contribute to a modest increase in horsepower. The filter’s design promotes smoother air intake, which can also result in a subtle improvement in engine sound, delivering a more aggressive intake note without excessive drone.

Installation & Fitment

Installation is straightforward and requires no modifications. The filter is a direct replacement for the factory air filter in 2011–2021 Jeep Grand Cherokee and 2011–2026 Dodge Durango models equipped with 5.7L Hemi and 6.4L 392 engines. Simply remove the old filter and insert the AEM DryFlow filter into the air box. Regular cleaning is recommended to maintain optimal performance.
