Key Features

The aFe Magnum FLOW Pro DRY S Air Filter combines advanced materials and design to provide superior filtration and airflow. Key features include:

• Constructed with 100% polyurethane on all four sides for a durable, leak-proof seal
• Two layers of progressively finer synthetic mesh media for maximum filtration efficiency
• Oil-free design eliminates the need for messy oil application and simplifies maintenance
• Washable and reusable, supporting multiple cleaning cycles for long-term use
• Tall, open, evenly spaced pleats increase surface area for excellent dust holding capacity
• Integrated urethane bump seal ensures a tight, no-leak fit throughout the filter’s lifespan
• Direct OE replacement, designed to fit perfectly without modifications

Construction & Design

The Magnum FLOW Pro DRY S Air Filter features a robust construction with 100% polyurethane framing on all sides, providing a flexible yet secure seal that prevents unfiltered air from entering the engine. The dual-layer synthetic media is engineered to trap contaminants effectively while maintaining high airflow rates, ensuring your engine breathes easier and performs better.

The tall pleat design maximizes the filter’s surface area, allowing it to hold more dust and debris before requiring cleaning. This design extends service intervals and helps maintain consistent engine performance over time. The oil-free synthetic media also reduces maintenance complexity and environmental impact compared to traditional oiled filters.

Performance & Sound

By increasing airflow and reducing restriction compared to the stock paper filter, the aFe Magnum FLOW Pro DRY S Air Filter helps improve throttle response and engine efficiency. While primarily focused on filtration and airflow, this upgrade can contribute to a subtle enhancement in engine sound, delivering a cleaner intake tone without excessive noise.

Installation & Fitment

This air filter is designed as a direct OE replacement for the 2008–2014 Scion xD, requiring no modifications for installation. It fits seamlessly into the factory airbox, maintaining a secure and leak-free seal thanks to its integrated urethane bump seal.
