aFe Momentum Replacement Air Filter with Pro DRY S Media, Part Number 20-91211D

This filter features three layers of oil-free synthetic media and requires no oil during maintenance to provide maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while its inverted top makes for more filter surface area, resulting in longer service intervals. This media is best suited for street and light off-road use. Pro DRY S filters are easily recharged with aFe's POWER CLEANER. 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. 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. 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.

Restore the filtration performance of your aFe POWER Momentum intake system with the aFe 20-91211D replacement air filter. Designed for street and light off-road use, this reusable filter uses three layers of progressive oil-free synthetic Pro DRY S media to provide efficient filtration, strong airflow, and excellent dust-holding capacity without requiring filter oil during maintenance.

The filter’s rounded, evenly spaced pleats increase usable media surface area for improved airflow and longer service intervals. Its inverted top further expands the filtration area, while the deep, open pleat design helps capture more dust before cleaning is required. The washable, reusable construction supports multiple cleaning cycles, and the filter can be recharged with aFe POWER CLEANER when needed.

Built with a 100% polyurethane base and top, the aFe 20-91211D maintains its molded shape through repeated engine-bay heat cycles better than many alternative materials. External locking tabs allow the filter to snap into compatible Momentum series housings without additional hardware, simplifying installation, replacement, and routine maintenance. A stainless steel clamp is included. This filter is intended as a replacement component for select aFe POWER Momentum intake systems; verify the original filter style and vehicle application before ordering. This product carries a California Proposition 65 warning.
