• Specification

• Function

1.Air Conveyance: As an important part of the engine's intake system, the 6743-11-4910 hose is responsible for conveying air. It connects components such as the air filter, turbocharger, and intercooler. Specifically, it transports the air compressed by the turbocharger to the intercooler for cooling, and then delivers the cooled air to the engine's intake system, ensuring that the engine receives a sufficient amount of clean and cooled air to support the combustion process.

2.Reducing Airflow Resistance: The inner surface of the hose is designed to be smooth, which helps to reduce airflow resistance. This allows the air to flow through the hose more smoothly, improving the intake efficiency. A smooth air flow is beneficial for ensuring the normal operation of the engine and enhancing its performance, as it can enable the engine to obtain a sufficient amount of air in a timely manner during operation, thereby ensuring efficient combustion and power output.
