aFe Momentum Replacement Air Filter with Pro DRY S Media, Part 21-90111

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 cleaned with aFe 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. Its surrounded by expanded metal that provides additional protection, preventing filter collapse and direct impact. 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.

The aFe Power 21-90111 Momentum replacement air filter is designed for street and light off-road applications where dependable filtration, convenient maintenance, and consistent airflow are important. Its three-layer, oil-free Pro DRY S synthetic media captures dirt and debris without requiring filter oil, simplifying cleaning and service. The progressive media construction balances filtration efficiency with strong dust-holding capacity to help support longer service intervals.

A rounded, evenly spaced pleat design increases usable media surface area for improved airflow and greater contaminant capacity. An expanded-metal support screen helps protect the media from direct impact and helps prevent filter collapse under demanding conditions. The inverted top further increases available filter surface area. The filter uses molded polyurethane for the base and top, helping it retain its shape through repeated engine-bay heat cycles. It is washable and reusable through multiple cleaning cycles with aFe Power Cleaner.
