Why choose this intake duct? The 712W08201-1910 is not just a replacement part; it is a performance upgrade. Manufactured from high‑density polymer composite with reinforced ribs, it withstands under‑hood temperatures up to 150°C and resists oil mist, dust, and vibration. Its internal geometry is optimized to reduce pressure drop by 12% compared to generic ducts, giving your engine a cleaner, denser air charge for better combustion and fuel economy.
Precision fit for HOWO and Sitrak – this duct assembly directly replaces the equipment with zero modification. It matches the mounting points, hose connections, and sensor ports of the latest HOWO T7, Sitrak C7, and the popular HOWO A7 series. Whether you are maintaining a fleet or rebuilding an engine, the 712W08201-1910 ensures integration and eliminates guesswork.
p Built for severe conditions: From Australian outback haulage to Siberian winter roads, this intake duct maintains structural integrity. The material has passed 500+ hours of salt‑spray and thermal shock testing. With a internal bore that resists soot buildup, it keeps the MAF sensor clean and turbo spool responsive.
Reduced ultra- intake restriction directly translates to improved throttle response and lower EGTs. Fleet tests show up to 3.2% fuel saving on long‑haul routes when combined with a clean air filter.
Turbo spool-up 15% faster in low‑RPM scenarios.
With a projected lifespan of over 1.2 million km under normal service, this duct reduces downtime. The precision‑molded sealing lip eliminates air leaks that cause turbo lag.
Easy 30‑minute replacement with basic hand tools.
The air intake system is the lungs of your diesel engine. A compromised duct leads to increased particulate emissions, higher fuel consumption, and premature turbo wear. That is why we engineered the 712W08201-1910 with computational fluid dynamics (CFD) to balance flow velocity and static pressure. The result: air delivery even at peak torque output.
Every duct undergoes 100% dimensional inspection and pressure‑drop validation before packaging. We use laser‑welded fuel- seams (where applicable) and a proprietary anti‑static inner coating that repels dust and moisture – a feature rarely found in aftermarket alternatives.
Direct replacement for part numbers 712W08201-1910, WG9725520100, and 81.96301.0023. Fits all HOWO T7H, Sitrak C7H, and the new energy‑optimized HOWO MAX models. No adapter or gasket required; the integrated O‑ring provides a seal. Torque the hose clamps to 8‑10 N·m for clamping.
To maximize the service life of your intake duct assembly, inspect the duct every 50,000 km for cracks or abrasion. Ensure the air filter housing is securely mounted to prevent excessive movement. Use only OEM‑spec hose clamps to avoid pinching the duct wall. When cleaning the engine bay, avoid high‑pressure water directly on the duct joints.
We recommend replacing the duct whenever you overhaul the turbocharger or replace the intercooler. A fresh duct ensures that the new turbo receives clean, unrestricted air, preventing early failure due to foreign object damage.
This intake duct is stocked in multiple warehouses across North America, Europe, and Asia-Pacific. Most orders ship within 24 hours. The part is also available in bulk packaging for fleet operators, with volume discounts and customized labeling upon request.
For workshop owners, we provide a comprehensive fitting guide and torque specs. The duct’s design reduces shipping costs and makes it easy to handle during installation.
Each duct is individually tested for leakage at 2.5 bar pressure. We provide a 12‑month warranty against manufacturing defects. The material is UL94 V‑0 rated for flame resistance, adding an extra layer of safety.

Final checklist: When replacing your intake duct, always inspect the connecting hoses and turbo inlet for debris. Use a torque wrench on the clamp bolts to prevent overtightening. This duct is compatible with both left‑hand and right‑hand drive configurations. For extreme dust environments, consider pairing it with a cyclone pre‑filter.
With more than 2,000 units already deployed in the field, the 712W08201-1910 has proven its reliability in mining, construction, and long‑distance transport. Upgrade your HOWO or Sitrak today with an intake duct that delivers factory‑fresh performance and long‑term value.
