The Air Inlet Tube is a component of air intake system. Its purpose is to provide a path for outside air to enter the engine's air filter housing. The tube is typically made of plastic or metal and may feature ribbing or other design elements to prevent collapse under vacuum pressure. It is mounted between the grille and the air filter box, directing cool, clean air into the engine for optimal performance. The Air Inlet Tube plays an important role in maintaining proper airflow through the engine and preventing contaminants from entering the system, helping to ensure reliable operation over time.
