Gain a competitive edge in structural design using MasterSeries 3D printed lattice structures drive innovation in manufacturing 3D Flat Slab Design {2025 Structural Guide} Structural Basics Full article: Natural cellular structures in engineering designs built lightweight structural supports using metal 3D printing MET3DP. Pro GUARD 7 Filter Media: This filter features seven layers of hybrid media for maximum protection. The patented combination of oiled cotton gauze with synthetic material allows this media to thrive in the dustiest and dirtiest environments imaginable. Pro GUARD 7 filters are easily recharged with aFe's POWER CLEANER and gold air filter oil. Click here for more information about our filter media. Rounded Deep Open Pleats: aFe POWER performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. Progressive Bump Seal: This pliable sealing surface conforms to even the most uneven filter housing, making for a perfect filter fit and sealing surface every time. This design eliminates the use of gaskets or sealants and always goes back to its original form. Full Polyurethane Frame: All aFe POWER flat panel performance air filters are constructed with a full 360 degree polyurethane frame. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape. Washable Foam Pre Filter: Just like our air filters, this 1 2 open cell polyurethane foam Pre Filter is washable and reusable. Easily remove the ABS plastic retainer (patent pending) and foam Pre Filter then just simply tap to remove excess debris between your usual cleanings. The foam Pre Filter can also be washed with aFe POWER Cleaner when you service your air filter. Extended Filter Life: Pre Filters provide added peace of mind for those who operate their vehicle in dirty environments. This foam pre filter captures large particles before they reach the air filter increasing efficiency and dust holding capacity, without negatively affecting airflow.
