The function of air system is allowing air to reach your car engine. Oxygen in the air is one of the necessary ingredients for the engine combustion process. A good air system allows for clean and continuous airflow into the engine, thereby achieving more power and better mileage for your car.

The cold air intake tube marks the beginning of air’s passage through the air intake system, the only opening through which air can enter. Air from outside the engine bay is typically lower in temperature and denser, therefore richer in oxygen, which is better for combustion, power output, and engine efficiency. Well-designed intakes use heat shields to isolate the air filter from the rest of the engine compartment, providing cooler air from the front or side of the engine bay.
