A device attatched to a car- usually at the rear, that changes the aerodynamic shape of a vehicle, reduces drag- which does not add downforce- and acts as a rear diffuser, eliminating a vacuum effect at the rear end of the car and improving gas milage.
Often mistaken for a wing or airfoil, which does the opposite by creating drag.
Before you hit that down button, google wing vs. spoiler.
Often mistaken as a type of airfoil or wing, spoilers do not increase down force of the rear wheels, but actually reduce it.
