The aFe MagnumFLOW OEM Replacement Air Filter with Part Number AFE31-10238 is designed to deliver reliable performance and long-lasting service for select BMW models. Constructed with a durable 100-percent polyurethane boxed frame, this filter ensures a tight, leak-proof seal with its integrated urethane bump seal, maintaining optimal airflow and filtration efficiency throughout its lifespan. Featuring three layers of progressive synthetic (dry) media, the filter maximizes dust holding capacity, reducing the frequency of cleanings and enhancing engine protection. Its tall, evenly spaced pleats provide a larger surface area for dust and debris capture, resulting in excellent filtration performance and longer service intervals. The filter is washable and reusable, allowing for multiple cleaning cycles without compromising its filtering capabilities, making it a cost-effective and environmentally friendly choice for BMW enthusiasts.
Designed specifically for BMW models including the M2 Competition, M3, M4, M5, M6, and M8 from 2012 to 2021, this filter ensures a perfect fit and optimal performance. Its high-quality synthetic media helps maintain maximum airflow, promoting better engine response and efficiency. Easy to install, the aFe MagnumFLOW filter is an excellent upgrade over stock filters, providing enhanced filtration without sacrificing airflow. Whether you're replacing a worn-out filter or upgrading for improved performance, this product offers dependable service and peace of mind for your vehicle*s filtration system. Proper maintenance and regular cleaning can extend the life of both the filter and your engine, ensuring consistent performance over time.
