With up to a 53% increase in flow over stock, this Pro 5R air filter features factory-oiled media for maximum performance. Its progressive bump seal design and polyurethane frame makes it extremely durable and simple to install.
Pro 5R Filter Media:
This filter features five layers of pre-oiled cotton gauze media 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 easily 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 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.
This product does not require a CARB EO#.
