SINOTRUK HOWO New Air Inlet Parts Model Wg9725190002

The Intake Duct Assembly (Part No. WG9725190002), commonly known as the Dual Intake Tube or Twin Cyclone Air Duct, is a core component of the air induction system on Sinotruk (China National Heavy Duty Truck Group Co., Ltd.) HOWO series heavy-duty trucks. This assembly connects the air filter outlet to the engine intake manifold, delivering clean, filtered air to the turbocharged diesel engine under high-flow conditions.

Featuring a distinctive dual-tube "telescope" design, this duct incorporates cyclonic pre-cleaning technology that separates large dust particles and debris from incoming air before it reaches the engine — significantly improving filtration efficiency and extending engine life, especially in harsh environments such as mining, construction, and off-road operations.
