Construction & Design

The Magnum FLOW Pro DRY S Air Filter features a robust build with a 100% polyurethane frame that resists cracking and deformation under heat and vibration. The synthetic media is engineered with three layers of mesh that progressively trap finer particles while maintaining high airflow rates. This layered design balances filtration efficiency with performance, protecting your engine from contaminants without restricting air intake.

The tall pleats increase the surface area, allowing the filter to hold more dust and debris before requiring cleaning. The integrated urethane bump seal provides a consistent, airtight fit that prevents unfiltered air from bypassing the filter, ensuring your engine breathes clean air at all times.

Performance & Sound

By replacing the restrictive stock paper filter with the aFe Magnum FLOW Pro DRY S, drivers can expect improved throttle response and a modest increase in horsepower and torque due to enhanced airflow. The oil-free synthetic media maintains consistent performance without the risk of oil contamination, which can sometimes affect mass airflow sensors. While the filter primarily focuses on airflow and filtration, some users may notice a subtle enhancement in intake sound, contributing to a more engaging driving experience.

Installation & Fitment

Designed as a direct OE replacement, the aFe Magnum FLOW Pro DRY S Air Filter installs easily into the factory airbox of 2004–2006 Scion xA and xB models without any modifications. The integrated urethane bump seal ensures a snug fit, preventing air leaks and simplifying the installation process. Routine maintenance involves removing the filter, washing it with a mild detergent or aFe’s cleaning solution, and reinstalling it once dry.
