Enhance your BMW*s performance with the aFe MagnumFLOW OE Replacement Air Filter, designed specifically for models such as the 135i, 335i, and X1 equipped with the N55 3.0L twin-turbo engine. Crafted with a 100% polyurethane boxed frame, this high-flow filter offers superior airflow compared to stock filters, resulting in improved horsepower and torque. Its five layers of progressively finer mesh cotton gauze media maximize airflow while maintaining excellent dust holding capacity, which means longer intervals between cleanings and sustained engine performance. The tall, evenly spaced pleats provide increased surface area for dirt filtration, ensuring optimal filtration efficiency. An integrated urethane bump seal guarantees a tight, leak-proof fit throughout the filter*s service life, maintaining engine integrity and performance over time. This washable and reusable filter is engineered for durability, allowing multiple cleaning cycles without sacrificing performance, making it a cost-effective upgrade for your vehicle. Designed to meet or exceed OE standards, the MagnumFLOW filter is an excellent choice for drivers seeking increased airflow and engine efficiency without compromising on quality. It is compatible with a range of BMW models from 2011 to 2013, including the 135i, 135is, 335i, 335is, and X1, ensuring a precise fit and reliable performance. Whether you're enhancing your daily driver or optimizing a performance build, this filter provides a significant upgrade over stock options, contributing to a more responsive and powerful driving experience. Please note this product is not CARB-approved but complies with Prop 65 requirements, ensuring safety and quality standards are met.
