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.

100% Polyurethane Base & Top:
This aFe POWER performance air filter is constructed with a polyurethane base and top. This construction allows for a proper factory style fit with excellent filter strength. Its inverted top makes for more filter surface area, resulting in longer service intervals.

Innovative Design:
Utilizing the filter's retention groove, the filter locks into most Stage-2 housings with zero hardware. This simple design allows for easy filter maintenance and replacement.
