Pro 5R Filter Media:
This filter features five pre-oiled cotton gauze media layers to provide maximum performance. Its progressive layering allows the filter to flow at high levels, even when dirty. This media is perfect for street and/or track use. Pro 5R filters are quickly recharged with aFe's POWER CLEANER and blue air filter oil.

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 more significant 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 gaskets or sealants and always returns to its original form.

Full Polyurethane Frame:
All aFe POWER flat panel performance air filters are constructed with a full 360-degree polyurethane frame. Polyurethane maintains its original molded shape, unlike other materials that degrade after repeated heat cycles in an engine bay.
