Product Description

The AEM 21-2029BF is a Brute Force Dryflow air filter engineered for tough off-road applications where dust capacity and durability matter as much as airflow. Its non-woven synthetic media delivers strong filtration efficiency while remaining completely oil-free, protecting sensitive intake components like MAF, MAP, and IAT sensors from oil contamination that can affect oiled cotton-gauze filters.

Built with a tapered conical shape, a 2.75-inch flange, and internal structural support, this filter is designed to hold its form under severe abuse rather than collapsing or deforming over time. It's washable and reusable, making it a practical long-term choice over disposable paper filters for custom intake builds, off-road rigs, and other universal fitment applications.

Since this is a universal-fit filter rather than a vehicle-specific part, confirm that your intake tube or housing uses a compatible 2.75-inch inlet before ordering, and be prepared for some adaptation depending on your specific setup.
