The Air Inlet Tube is a component of air intake system that connects the air filter housing to the engine's throttle body. Its purpose is to allow clean air to flow into the engine while keeping out dirt and other contaminants. The tube is typically made of plastic or metal and may have bends or curves to fit within the limited space available in the engine compartment. A damaged or clogged air inlet tube can cause reduced engine performance, increased fuel consumption, and potential damage to other components in the intake system. Regular inspection and maintenance of this part can help ensure optimal engine performance and longevity.
