For heavy‑duty trucks operating in dusty environments, a reliable air filtration system is essential to protect the engine from abrasive particles and extend its service life. The WG9725193310 OIL BATHAIR FILTER ASS HOWO 371HP from HOWO is engineered to deliver exceptional cleaning efficiency, robust construction, and a perfect factory fit, ensuring that your engine breathes clean, filtered air in the most demanding operating conditions. As a vital Howo/Sitrak truck parts component, this oil bath air filter assembly is designed with a multi‑stage filtration system that uses oil to capture dust, pollen, and other contaminants, providing superior dust‑holding capacity compared to conventional dry filters. Its durable steel housing and corrosion‑resistant finish ensure long‑term reliability, even in harsh off‑road environments. Whether you are replacing a worn‑out filter assembly or upgrading your air intake system, the WG9725193310 guarantees OEM‑spec performance, extended engine life, and reduced maintenance costs – making it the trusted choice for professional workshops and fleet operators worldwide.
The oil bath air filter assembly is a time‑tested, highly efficient filtration solution that is particularly effective in extreme dust environments. The WG9725193310 works by drawing air through a reservoir of oil, where heavier particles are trapped, and then passing the air through a series of mesh elements that capture finer dust. This design offers several advantages over traditional dry paper filters: it has a much higher dust‑holding capacity, can be cleaned and reused, and is less prone to clogging in humid or wet conditions. HOWO has engineered this assembly with a precision‑formed steel body, a robust oil reservoir, and a stainless‑steel mesh that ensures optimal oil circulation and filtration efficiency. The assembly also features a built‑in safety indicator that alerts the driver when cleaning or oil replacement is needed. By using the WG9725193310, you ensure that your engine receives consistently clean air, reducing wear on pistons, rings, and cylinder walls, and extending the overall lifespan of your powertrain.

The WG9725193310 oil bath air filter assembly is a masterpiece of robust and efficient design. Its housing is manufactured from high‑strength steel and finished with a corrosion‑resistant coating, ensuring that it withstands the harsh conditions of off‑road operation, including impacts, vibration, and exposure to chemicals. The internal oil reservoir is carefully shaped to promote optimal oil circulation and dust settlement, while the stainless‑steel mesh elements provide a large surface area for fine particle capture. The design incorporates a safety indicator that visually signals when the filter requires servicing, preventing the risk of neglect. The assembly is also equipped with a secure sealing system that prevents unfiltered air from bypassing the filtration media. Every unit is tested for airflow, filtration efficiency, and sealing integrity, guaranteeing that the WG9725193310 meets HOWO’s demanding quality standards. This engineering excellence translates into superior engine protection, reduced downtime, and lower operating costs over the long term.
The WG9725193310 is specifically designed for HOWO T7H and A7 trucks equipped with the 371HP (MC11/MC13) engine, as well as many Sinotruk models that share the same air intake system. It directly replaces the original oil bath filter assembly with identical mounting points, port diameters, and overall dimensions, ensuring a straightforward bolt‑on installation without modifications. The assembly is compatible with all standard air intake hoses and clamps.
To confirm fitment, always cross‑reference the OEM number on your existing assembly with WG9725193310. If they match, this component will integrate seamlessly. Keeping this filter assembly in your spare parts inventory enables rapid air system servicing, minimising downtime and maintaining your engine’s performance and longevity.

Replacing a clogged or outdated air filter with the WG9725193310 immediately restores the full airflow capacity to your engine. The efficient oil‑bath design ensures that even the finest dust particles are captured, preventing abrasive wear on cylinder liners, piston rings, and valves. This results in sustained compression, reduced oil consumption, and consistent power output. The reusable nature of the oil bath filter also offers significant cost savings over time, as it can be cleaned and re‑oiled multiple times before replacement is needed – a distinct advantage over disposable dry filters. The robust construction also reduces the risk of filter damage from stone impact or vibration, extending its service life. For fleet operators, the use of a genuine HOWO oil bath filter reduces unscheduled maintenance, lowers total cost of ownership, and improves overall vehicle reliability. By investing in the WG9725193310, you ensure that your engine breathes clean, filtered air, delivering the maximum performance and durability that your HOWO truck is renowned for.
Installing and servicing the WG9725193310 oil bath air filter assembly is straightforward. For installation, begin by safely supporting the vehicle and removing the old filter assembly. Clean the mounting surfaces and inspect the intake hoses for damage. Position the new assembly and secure it with the original mounting bolts, torquing them to specification. Connect the intake and outlet hoses, ensuring they are properly seated and clamped. Fill the oil reservoir with the recommended grade of engine oil (typically SAE 30 or 40) to the specified level. Start the engine and check for any air leaks. For servicing, periodically drain the dirty oil, clean the mesh elements with a suitable solvent, rinse and dry them, then refill with fresh oil. The service interval depends on operating conditions, but should be checked at regular intervals. With proper maintenance, the WG9725193310 will provide reliable filtration for many years.
Pro Tip: When servicing the oil bath filter, always use the recommended oil viscosity and ensure the oil level is correct. Too much oil can cause oil carryover into the engine, while too little reduces filtration efficiency. The WG9725193310 is designed for easy servicing – follow the instructions in your vehicle’s maintenance manual for best results.
Genuine HOWO components are engineered to the highest standards, and the WG9725193310 Oil Bath Air Filter Assembly is no exception. Aftermarket filters often use inferior steel, poor‑quality mesh, or inadequate sealing, leading to reduced filtration efficiency, oil leaks, and premature engine wear. HOWO’s assembly is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance.
By choosing the WG9725193310, you benefit from HOWO’s rigorous testing, including airflow, filtration efficiency, and vibration tests that simulate millions of kilometres of real‑world operation. This ensures that the filter assembly meets the demanding requirements of heavy‑duty trucking. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global network, giving you confidence in your purchase and long‑term peace of mind.
