Can you run a car without air box?
Can a Car Start Without an Air Filter? A car can start just fine without an air filter installed – initial power is supplied by the car battery and air from the atmosphere can still be sucked in (even better air flow without air filter). So if your car is not starting, it's not because of a missing air filter.
What does the air box do in a car?
An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder. Older engines drew air directly from the surroundings into each individual carburetor.
