Key Features

The aFe MagnumFLOW Pro 5R Air Filter combines advanced materials and thoughtful design to maximize airflow and filtration. Key features include:

Construction & Design

The MagnumFLOW Pro 5R Air Filter is constructed with five layers of progressively finer cotton gauze media, which effectively traps contaminants while allowing maximum airflow to the engine. The cotton gauze is oiled to enhance particle capture without restricting air intake. The filter’s tall, open pleats increase surface area, improving dust capacity and reducing airflow restriction compared to conventional paper filters.

Its robust polyurethane end caps and frame provide durability and maintain the filter’s shape under demanding conditions. The integrated urethane bump seal creates a secure, leak-proof interface with the factory airbox, preventing unfiltered air from entering the intake system and ensuring consistent performance throughout the filter’s service life.

Performance & Sound

By improving airflow over the stock paper filter, the aFe MagnumFLOW Pro 5R enhances engine breathing, which can lead to noticeable improvements in horsepower and torque. This increased airflow also contributes to sharper throttle response and smoother acceleration. Despite its performance focus, the filter maintains the factory intake sound characteristics without introducing excessive intake noise, preserving the Jeep’s natural engine tone.

Installation & Fitment

Installation is straightforward and requires no modifications to the vehicle’s factory airbox or intake system. The filter is designed to fit perfectly into the original equipment housing of the 2007–2011 Jeep Wrangler 3.8L V6. Simply remove the old paper filter and replace it with the aFe MagnumFLOW Pro 5R for an immediate upgrade in airflow and filtration performance.
