How often should the Envision's intake tract be cleaned?

[StJoshua]

The Envision's intake tract cleaning interval can be every six months or 20,000 kilometers. If there is accumulated debris on the throttle body, cleaning should be performed as needed. Every six months or 20,000 kilometers: Cleaning the intake system every six months or 20,000 kilometers is standard practice. The engine's intake system serves as the gateway for air entering the combustion chamber. Due to the engine's operating environment and airborne impurities being drawn into the intake system for combustion, carbon buildup becomes a primary concern. Throttle body with accumulated debris: If the vehicle operates in highly polluted environments (primarily referring to inhalable particulate matter), debris can quickly accumulate on the throttle body. Over time, this affects engine intake, necessitating cleaning. This issue is most noticeable when starting the vehicle. Depends on circumstances: The cleaning frequency depends on various factors, such as the vehicle's driving environment and the fuel injection system's adjustment method.
