Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | Air Inlet Pipe Assembly / Air Intake Duct / Air Filter Inlet Hose |
| OEM Number | WG9725190904 |
| Alternate Part Numbers | WG9725190902, WG9725191904 (similar variants) |
| Position | Connects external air intake (hood/side inlet) to air cleaner/filter box |
| Material | High-grade UV-resistant engineering plastic (modified polypropylene or PP-TD30) |
| Design Type | Molded shape with smooth internal bore for low-restriction airflow |
| Sealing Mechanism | Rubber gaskets, silicone seals, and clamp rings at both ends |
| Function | Channels ambient air into the air filtration system before reaching the engine |
| Flow Optimization | Designed with aerodynamic curvature to minimize pressure drop |
| Operating Environment | Resists vibration, thermal cycling (-30°C to +90°C), and road debris |
| Condition | Brand new (OEM fresh stock or premium aftermarket) |

Verify Compatibility Before Purchase
Match your truck model, engine type (WD615), and air filter box design.
Some HOWO A7/T7H variants have slightly different duct shapes.
Inspect All Connection Points
Clamps
Rubber gaskets
Mounting brackets
Check condition of:
Replace worn parts to ensure airtight seal.
Ensure Proper Alignment During Installation
Align pipe with air intake port and filter housing.
Do not force-fit — misalignment can crack joints.
Secure All Fasteners
Tighten hose clamps to recommended torque (~2–3 Nm).
Loose connections suck in unfiltered air.
Avoid Kinks or Restrictions
Keep intake path straight and free from crushing or bending.
Obstructions reduce airflow and hurt engine performance.
Keep Clean and Unobstructed
Regularly remove leaves, insects, ice, or snow from outer intake.
Clogged intake reduces air supply and increases EGT (exhaust gas temperature).
Check for Cracks or Brittle Areas
Especially near bends or mounting points.
Old plastic becomes brittle in sunlight — replace proactively.
Do Not Use Adhesives or Tape
Never patch cracks with glue or tape — risks foreign object ingestion.
Always replace with genuine or high-quality unit.
Transportation & Packaging
Fragile molded plastic — must be shipped in reinforced cardboard box with foam padding.
Handle carefully to avoid chipping or warping.
Storage Advice
Store flat in dry indoor environment.
Keep away from direct sunlight and extreme temperatures.
