Conversely, rough inner surfaces lead to turbulence in the airflow, resulting in decreased engine power. High-temperature stability Ordinary rubber gradually softens at high temperatures, which decreases the inner diameter of the pipe. The engine may then experience idling jerks and weak acceleration. Intake duct tubes with insulating layers can control the intake air temperature, ensuring stable air density and full combustion. Sealing If the material is not properly sealed, unfiltered, high-temperature air will lead to accelerated impurity wear and tear of the engine and imbalance of the mixture, resulting in power loss.
