aFe Power Momentum Replacement Air Filter with Pro 5R Media, Part Number 20-91211R

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, while its inverted top makes for more filter surface area, resulting in longer service intervals. 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. 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.

The aFe Power Momentum replacement air filter with Pro 5R media is designed to restore airflow and filtration performance in compatible aFe Power Momentum intake systems. Part Number 20-91211R uses five layers of progressively arranged, pre-oiled cotton gauze to support high airflow, even as the filter accumulates dirt. The inverted top increases usable filter surface area, helping extend service intervals for street and track applications.

Rounded, evenly spaced pleats provide additional filtration area and dust-holding capacity, while the polyurethane base and top resist deterioration caused by repeated engine-bay heat cycles. The molded polyurethane construction helps the filter retain its shape through extended use. External locking tabs allow the filter to snap into most compatible Momentum intake housings without additional hardware, supporting quick installation, maintenance, and replacement.

The washable and reusable Pro 5R filter can be serviced through multiple cleaning cycles using aFe Power Cleaner and blue air filter oil. This replacement filter includes a stainless steel clamp and is intended for automotive applications using a compatible aFe Power Momentum intake housing. Verify intake system compatibility before installation. This product is not CARB approved where applicable, and a required emissions acknowledgement may apply.
