Air Filter Intake Connecting Pipe
The official part number for this component is LZ970419000013.

1. Basic Part Information

• Part Name: Air Filter Intake Connecting Pipe (commonly known as "air filter intake hose" or "intake elbow")

• Part Number: LZ970419000013

• Brand Marking: The bottom right corner of the image shows a stamp with the Sinotruk logo, along with the part number and ID code (ID: 37.01.00D12), which is a typical feature of genuine Sinotruk parts.

• Appearance Features:

  • Material: Made of black, high-strength engineering plastic (e.g., PP or PE material), injection-molded as a single piece, offering high temperature resistance, corrosion resistance, and anti-aging properties.

  • Structure: S-shaped curved design with a flared end and bolt holes for securing to the air filter housing; the other end connects to the engine air intake or related piping.

  • Special Design: The pipe opening features a black, mesh-like rain cover/insect screen to prevent rain, leaves, insects, and other foreign objects from being sucked into the intake system.

2. Applicable Models & Installation Position

• Applicable Models: Mainly suitable for Sinotruk HOWO light truck series, such as Hanjiang, Tongshuai, Wangpai, and other models.

• Installation Position: Located between the air filter (air filter housing) and the engine intake pipe. It serves as the "throat" of the engine intake system, guiding filtered, clean air into the engine combustion chamber.

3. Main Functions & Role

• Air Guidance: The specific curved angle design ensures a reasonable spatial layout between the air filter and the engine, allowing smooth air flow.

• Rain & Debris Protection: The mesh cover at the top effectively prevents rainwater backflow and blocks some large particles, protecting the engine cylinder and piston rings from wear.

• Vibration Damping & Noise Reduction: The plastic material provides some sound-absorbing effect, reducing noise generated by intake airflow.
