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. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape.

Innovative Design:
Utilizing the filter's external locking tabs, the filter snaps into most Momentum series housings with zero hardware. This patent pending interface allows for easy filter maintenance and replacement.

Fitment Note:
This item fits aFe POWER cold air intakes 50-70032D
