Upgrade your BMW with the aFe MagnumFLOW OE Replacement Air Filter featuring Pro 5R media, designed specifically for models from 1986 to 1994 including the 3 and 5 Series with inline-six engines. Constructed with a durable 100-percent polyurethane boxed frame, this high flow filter outperforms stock filters by significantly increasing airflow, which leads to improved horsepower and torque. Its five-layer, progressively finer mesh cotton gauze media ensures maximum airflow while maintaining excellent filtration performance. These tall, open, evenly spaced pleats provide a large dust holding capacity, allowing for longer service intervals between cleanings and sustained engine performance. The integrated urethane bump seal guarantees a tight, leak-proof fit throughout the lifespan of the filter, preventing unfiltered air from bypassing and ensuring optimal engine protection. This filter is washable and reusable, making it a sustainable choice for those seeking consistent performance and cost savings over time. Designed to fit a range of BMW models including 318i, 318is, 325i, 325is, and 520i, this filter is easy to install and engineered to deliver reliable, high-performance air filtration for your vehicle. With its proprietary media and robust construction, the aFe MagnumFLOW OE Replacement Air Filter provides a significant upgrade over stock filters, supporting improved engine efficiency and overall vehicle performance.
