A spoiler is a device intended to reduce drag by inducing turbulence and causing the laminar flow over a surface to separate sooner than it would without the spoiler.
A wing is a device which adds drag to generate lift--negative lift in automotive applications. The wings on F1 race cars create gobs of drag, because they also generate gobs of down force--4 to 5 times the weight of the vehicle.
The terms are used interchangeably, and therefore most often incorrectly, in automotive discussions--even so-called "authoritative sources" openly display their ignorance by blatantly mixing up and confusing the terms.
Here is a good Auto Aerodynamics 101 white paper...

I absolutely loved this write-up on aerodynamics!!!
I LMAO when reading that maybe we should not wax our cars but rather let them get hail damaged.
Although I expect the impact of such changes to be very low, I may experiment with closing off some of my front end openings, and adding a few washers to my hood hinges to allow a little air to exit from the rear of my engine compartment (for use at the drag strip). I totally buy into the notion that reducing the air flow from entering the engine compartment and then under the car is a very good thing. Since the Bullitts have no fog lights, I have additional openings for air to enter under the car.
THANKS for the link!!!
