aFe Air Filter

Dodge Durango 04-09 5.7L/4.7L

Part #: 31-10119

Overview

The aFe Air Filter for the 2004–2009 Dodge Durango is a high-performance replacement designed to upgrade your vehicle’s factory air filtration system. Engineered as a direct OE replacement, this air filter offers enhanced airflow and superior filtration compared to restrictive paper filters. Ideal for Durango owners seeking improved engine response, increased horsepower, and longer service intervals, the aFe Air Filter combines durability with efficiency for both daily driving and performance applications.

Whether you drive a stock or modified Durango, this filter ensures your engine breathes cleaner air, helping to maintain optimal combustion and power output while protecting vital engine components from dust and debris.

Key Features

Designed to deliver reliable performance and longevity, the aFe Air Filter includes the following key features:

• 100% polyurethane frame construction for superior strength and shape retention
• Integrated progressive bump seal that conforms to uneven housing surfaces, ensuring a tight, leak-free fit
• Rounded, evenly spaced pleats maximize surface area for enhanced airflow and dust holding capacity
• Washable and reusable design reduces replacement frequency and environmental impact
• Available in two media options to suit different driving needs: Pro 5R (oiled cotton gauze) and Pro DRY S (synthetic, oil-free)
• Extended cleaning intervals thanks to high dust holding capacity
• OE replacement fitment for easy installation without modifications

Filter Options

The aFe Air Filter is available in two distinct media configurations to match your driving style and maintenance preferences:

• Pro 5R (Oiled): Features five layers of progressively finer oiled cotton gauze for maximum airflow and filtration efficiency. Tested at 98.6% filtration efficiency, it is ideal for performance driving and heavily modified engines. This filter is washable and reusable for multiple cleaning cycles.
• Pro DRY S (Non-Oiled): Utilizes three layers of progressive synthetic media with an oil-free design for easy maintenance and maximum convenience. It maintains high airflow even in dusty conditions and is best suited for daily drivers and low-maintenance applications. Also washable and reusable.

Construction & Design

The aFe Air Filter is engineered with a robust 100% polyurethane frame that maintains its shape under all conditions, preventing collapse or deformation. This ensures a consistent seal and prevents unfiltered air from entering the engine. The progressive bump seal integrated into the frame adapts to uneven surfaces within the airbox, providing a leak-free installation.

The filter media is pleated in a rounded, evenly spaced pattern to maximize the surface area exposed to incoming air. This design not only improves airflow but also increases the filter’s dust holding capacity, extending the time between cleanings. Both media options are designed for durability and repeated wash cycles without compromising filtration performance.

Performance & Sound

By replacing the restrictive factory paper filter with the aFe Air Filter, your Dodge Durango benefits from improved airflow, which can contribute to increased horsepower and torque. The enhanced breathing capability supports better throttle response and engine efficiency. While the filter itself does not alter exhaust sound, the improved airflow can complement other performance upgrades for a more responsive driving experience.

Installation & Fitment

Installation of the aFe Air Filter is straightforward and requires no modifications. It is designed as a direct OE replacement for all 2004–2009 Dodge Durango models, fitting precisely into the factory airbox. Simply remove the old filter and install the aFe Air Filter, ensuring the progressive bump seal seats properly for a secure, leak-free fit.
