The invention provides an air intake 
system and a vehicle, and relates to the technical field of vehicles. The air intake 
system comprises an air 
damper and air intake manifold branches. The air 
damper is used for adjusting the air intake amount of air entering an engine. The air intake manifold branches are arranged above the air 
damper and communicate with the air damper. The 
pipe wall of each air intake manifold 
branch is provided with a first heating device used for heating the 
pipe wall of the air intake manifold 
branch, so that 
water vapor inside air is prevented from coagulating on theinner wall of each air intake manifold 
branch. By the adoption of the structure, the heating devices are arranged at the 
pipe walls of the air intake manifold branches and heat the pipe walls of the air intake manifold branches, the 
temperature difference between the inner walls of the air intake manifold branches and intake air is reduced or even eliminated, the temperature of the pipe walls is greater than or equal to the air intake temperature of air, vapor inside the air is prevented from coagulating on the inner walls of the air intake manifold branches to form 
frost, the source of condensate water is eliminated, freezing of the air damper is effectively avoided, and it is ensured that working is reliable when the engine is in 
cold start in 
cold winter.
