The aFe MagnumFLOW Pro 5R replacement air filter measures 2.5in inlet x 4.5in base x 4.5in top (inverted) x 7in height and uses five layers of pre-oiled cotton gauze for high flow even when dirty. Its progressive pleat design increases usable surface area and dust capacity, while polyurethane base and top resist heat-cycle degradation. The filter snaps into most Momentum housings and is serviceable with aFe POWER CLEANER and oil.
