aFe Power Momentum Pro DRY S Replacement Air Filter (5in F x 7in B x 5.5in T x 9in H) 21-91125

Maintain peak airflow and engine protection with this aFe Power Momentum replacement air filter (MPN 21-91125). Designed as a direct replacement for Momentum series intake systems, this conical performance filter utilizes Pro DRY S (PDS) media—an oil-free, 3-layer progressively finer synthetic mesh. This design provides 99.2% filtration efficiency and excellent dust holding capacity, allowing for longer service cycles without the need for filter oiling.

Constructed with 100% polyurethane on the top and base, this filter is built to withstand engine bay heat and vibrations. The pliable flange features integrated bumps to ensure a tight, leak-free seal against the intake housing for the life of the filter. Since the media is fully washable, it offers a sustainable, high-performance alternative to disposable paper filters.
