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.
