This vent will replace both the upper and lower vent in most Cessna 172. It is available in Black Anodized or Clear Coat Anodized and will attach to a 2” hose or the plastic cup that fit’s the lower vent with 1” hose. This vent flows more air and is much better quality than OEM.
Adapter cup not included. Reuse the cup from existing OEM vent.
