[ohhh my]

My car is lowered and over the weekend while looking under the car, I noticed the left side rubber piece circled below missing. This looks to be an air scoop.

Can someone verify what this part is? and provide a part number for the driver side?

Also, anyone know the part number for the plastic piece in front of the front driver side wheel and plastic piece in front of the rear passenger wheel too. I believe it's a deflector so wind or water won't go directly onto the tire..
