    Gen 9 General Discussion (Generation 9)
    I have a 2016 malibu with the 1.5t and i noticed that i dont get the fuel economy that i am expecting from the car. Now i purchased my car used and i realized the factory air dam that sits below the front bumper is missing from my car. I was wondering does the air dam affect fuel economy...
