For every heavy-duty SINOTRUK Howo truck, clean air is not a luxury—it’s the fundamental lifeblood of the engine. The first and most crucial line of defense for your engine’s intricate components is a high-quality air filter. As your trusted source for genuine Sinotruk howo parts, we present the essential **Air Filter Element**, precisely engineered under the OEM part number **WG9725190102+0103**. Also commonly identified as the **K2841** filter, this genuine component is tasked with a critical mission: to ensure only clean, contaminant-free air reaches the combustion chamber. Protecting your investment begins with the air it breathes, and choosing the authentic WG9725190102+0103 filter is a decisive step toward guaranteed performance, optimal fuel efficiency, and maximum engine longevity.

The air filter element, part number WG9725190102+0103, serves as the unwavering guardian of your SINOTRUK Howo’s engine. Positioned within the air intake system, its singular, vital purpose is to **remove harmful contaminants**—such as dust, dirt, pollen, and soot—from the air before it enters the engine. A heavy-duty truck operating on highways, construction sites, or rural roads ingests enormous volumes of air; even small amounts of abrasive particles can cause significant internal damage over time. The genuine K2841 filter is designed with a high-capacity, pleated media that provides an extensive surface area to trap these particulates efficiently while maintaining the unrestricted airflow essential for combustion.
Engine performance is directly linked to air quality. Clean air ensures the correct air-fuel mixture, leading to **efficient combustion**, **full power output**, and **lower fuel consumption**. Conversely, a clogged or substandard filter restricts airflow, creating a “rich” fuel mixture that wastes diesel, reduces horsepower, and causes excessive black smoke from the exhaust. Furthermore, unfiltered abrasive particles are the primary cause of wear on cylinder walls, piston rings, turbocharger blades, and other critical engine components. Therefore, the WG9725190102+0103 is not merely a maintenance item; it is a **cost-effective insurance policy** against premature engine wear and costly repairs.
The design and materials of the original filter are crucial. It is constructed from **high-grade solidified filter paper** and synthetic materials, engineered to withstand temperature variations and humidity without degrading. Its robust sealing edges, often made from polyurethane (PU), ensure a perfect fit within the filter housing, preventing “air bypass” where dirty air can sneak around the filter media. By choosing the genuine WG9725190102+0103 element, you are guaranteeing that the filtration performance meets the exact specifications set by SINOTRUK engineers for your Howo model.
Maximum Engine Protection & Longevity
The high-efficiency media in the WG9725190102+0103 captures over 99% of harmful dust and particulates, acting as a primary shield against abrasive wear for cylinders, pistons, and the turbocharger, significantly extending your engine’s service life.
Optimized Fuel Efficiency and Power
By ensuring clean, unrestricted airflow, this filter maintains the ideal air-fuel ratio for combustion. This results in consistent engine power, improved throttle response, and better overall fuel economy, directly reducing your operating costs.
Guaranteed Fit and Sealing Performance
Manufactured to exact OEM dimensions, the WG9725190102+0103 fits perfectly in the housing. Its PU sealing gasket prevents unfiltered air from bypassing the element, a common failure point in inferior filters that compromises all protection.
Durable Construction for Demanding Service
Built with quality solidified paper and robust materials, this filter is designed to handle high air volumes and challenging environmental conditions without collapsing or deteriorating, offering reliable protection throughout its service interval.

Recognizing the signs of a failing air filter is key to proactive maintenance. A clogged WG9725190102+0103 filter will cause a noticeable **loss of engine power and sluggish acceleration**, as the engine struggles to draw in enough air. You may observe **increased black or gray smoke** from the exhaust due to an overly rich fuel mixture. **Poor fuel economy** is a major financial indicator; if your Howo’s mileage drops without other explanation, the air filter is a primary suspect. In severe cases, the engine may **hesitate, misfire, or even stall** under load. Visually, a filter element that is dark gray, caked with debris, or has damaged pleats needs immediate replacement.
Replacing the air filter element is one of the simplest yet most impactful maintenance tasks. Locate the air filter housing, usually a large black plastic or metal canister on the side of the engine. Release the clamps or unscrew the wing nuts securing the cover. Carefully lift the old WG9725190102+0103 filter out. **Crucially, take this opportunity to thoroughly clean the inside of the filter housing and the intake tube** using a clean, damp cloth to remove any settled dust that could be ingested immediately after installation.
Before placing the new genuine filter in, inspect its rubber sealing gasket for integrity. Place it securely in the housing, ensuring it sits flat and the seal is properly seated all around. A misaligned filter will allow dirty air to bypass, rendering it useless. Reinstall the cover and fasten all clamps or nuts securely. There is no need for tools to be overly tight; secure is sufficient. **Do not attempt to clean and reuse a paper filter element** by tapping it or using compressed air, as this can damage the micro-porous structure and reduce its efficiency.
The replacement interval varies based on operating conditions. For trucks in extremely dusty environments (construction, mining, desert roads), inspect the filter every 10,000 km and replace it more frequently. Under normal highway conditions, follow the manufacturer’s recommended service interval, typically between 30,000 to 50,000 km, but always let visual inspection be your final guide. Using the genuine WG9725190102+0103 ensures you get the full service life and protection you pay for. Keeping a spare filter in your truck’s cabin is a wise practice for long hauls, ensuring you can always provide your engine with the clean air it needs for reliable, efficient, and powerful performance.
The Air Filter Element WG9725190102+0103 (K2841) stands as a silent sentinel for your SINOTRUK Howo’s engine. Its role in delivering clean air is a fundamental prerequisite for achieving the power, efficiency, and durability that heavy-duty trucks are built for. This component directly impacts your daily operating costs and the long-term health of your most valuable asset.
Never compromise on the quality of your engine’s first line of defense. Choosing the authentic WG9725190102+0103 guarantees optimal filtration performance, a perfect fit, and the peace of mind that comes with using a component designed and tested for your specific vehicle. It is a small, smart investment that pays substantial dividends in protected horsepower, conserved fuel, and extended engine life. Trust in genuine OEM parts to keep your Howo breathing cleanly and running strongly, mile after demanding mile.
