Key Features:

The aFe Magnum FLOW Pro 5R Air Filter incorporates advanced filtration technology and durable materials to maximize engine efficiency and longevity. Key features include:

• Five layers of pre-oiled, progressive cotton gauze media for maximum filtration and airflow
• Deep, open pleats that increase usable filter surface area, enhancing flow and dust holding capacity
• Rounded, evenly spaced pleat design to optimize airflow and filtration efficiency
• Durable polyurethane frame with a full 360-degree seal that resists heat and maintains shape
• Progressive bump seal design that conforms to uneven filter housings, ensuring a perfect fit without gaskets or sealants

• Factory-oiled media for immediate installation and maximum performance out of the box
• Up to 36% increased airflow compared to the OEM filter for improved engine response

Construction & Design:

The Pro 5R air filter is constructed with premium five-layer cotton gauze media that is pre-oiled to provide excellent filtration while allowing high airflow. The media’s progressive layering design ensures the filter maintains strong flow rates even as it collects dirt, making it suitable for both street and track environments.

The filter’s frame is molded from high-quality polyurethane, which resists degradation from heat cycles commonly experienced in engine bays. This material maintains its original shape and sealing properties over time, providing a reliable, long-lasting seal without the need for additional gaskets or adhesives.

The rounded pleat design increases the filter’s surface area, allowing it to trap more contaminants while minimizing airflow restriction. This thoughtful engineering results in a filter that balances protection and performance effectively.

Performance & Sound

By increasing airflow by up to 36% over the stock air filter, the aFe Magnum FLOW Pro 5R Air Filter helps improve throttle response and engine efficiency. Enhanced airflow can contribute to a more responsive driving experience, especially under demanding conditions such as spirited driving or track use. While primarily focused on filtration and flow, this upgrade may also subtly enhance engine induction sound, providing a more engaging auditory feedback without excessive noise.

Installation & Fitment:

Installation of the aFe Magnum FLOW Pro 5R Air Filter is straightforward and requires no modifications. The filter is designed to be a direct OE replacement for the factory air filter in the 2017–2020 Scion FR-S, Subaru BRZ, and Toyota 86 models with the 2.0L H4 engine. Its pliable sealing surface conforms perfectly to the airbox, ensuring a secure fit and airtight seal every time. This makes installation quick and hassle-free, suitable for DIY enthusiasts and professionals alike.
