The aFe MagnumFLOW Air Filter Part Number AFE21-90021 is designed to deliver exceptional airflow and filtration efficiency for your vehicle. Featuring three layers of progressively finer mesh synthetic media, this high-flow, oil-free conical performance filter ensures maximum dust holding capacity and long service intervals. The top and base are constructed from durable polyurethane, providing a robust foundation for the filter's structure. The tall open pleats are evenly spaced to facilitate unrestricted airflow while maintaining excellent dust retention, supporting consistent engine performance.
The pliable polyurethane flange with integrated bumps guarantees a tight, leak-proof seal throughout the filter's lifespan, preventing unfiltered air from bypassing the media. Washable and reusable, this filter can be cleaned multiple times, reducing maintenance costs and environmental impact. With a filter efficiency of 99.2%, it effectively captures airborne particles to protect your engine components from debris and wear.
Designed for ease of maintenance, the Magnum FLOW filter requires minimal effort to clean, making it suitable for both casual and enthusiast drivers. Its compact dimensions fit a variety of intake systems, ensuring versatility and compatibility. Whether you are upgrading your existing setup or building a custom intake, this filter provides the airflow and filtration performance needed for optimal engine operation and longevity.
