Designed by aFe, the MagnumFLOW OE Replacement Air Filter offers a reliable upgrade for your BMW models including the 2013-2014 528i, 2010-2013 Z4, and 2013 X1. Constructed with a durable 100-percent polyurethane boxed frame, this filter provides a secure fit and long-lasting performance. Its three layers of progressive synthetic (dry) media maximize dust-holding capacity and ensure a clean airflow, contributing to optimal engine efficiency and power. The tall, evenly spaced pleats increase surface area, allowing for longer intervals between cleanings. Its washable and reusable design enables multiple cleaning cycles, making it a cost-effective choice for maintaining peak engine performance. An integrated urethane bump seal guarantees a tight, leak-proof seal over the filter's lifespan, preventing unfiltered air from bypassing the media and protecting your engine from contaminants.
