Rubber duckbill valve
These are designed to attach to an airbox so if water is to enter the airbox, then the water is available to drain out.
Having these on your car allows you to do a water crossing without having to jump out and put a bolt into your airbox like other manufacturers products.
These attach to a piece of 32mm tube and use either a Ziptie or a Hoseclamp to hold it on.
