Abstract: A hood latch, hood and vehicle-mounting component that provide improved durability and aerodynamic properties as well as access to an under hood area. The latch is a two-part component. The latch is mounted under the hood and is only exposed where it latches to the latch catch on the vehicle-mounting component.
