Like your body, your car's engine needs rest because continuous combustion from everyday and long-distance driving might cause it to burn out. To keep that from happening, you must get your car a cold air intake system if it doesn't have one yet. This will keep the temperature of your engine down by allowing more oxygen into it, thereby maximizing combustion and making the burning of fuel become more efficient. It will in save you on gas, boost your horsepower, and stretch the life of your internal-combustion engine.
