The AZ87351600100 air filter (ХИЙН ХУВААРЬЛАГЧ) is not just a replacement part – it is a critical safeguard for your engine’s internal components. In heavy‑duty applications, engines ingest massive volumes of air daily, along with abrasive dust, silica, and other particulates that can cause catastrophic wear if not properly filtered. This genuine HOWO filter uses a high‑density micro‑fiber media that captures over 99.5% of particles as small as 5 microns, ensuring that only clean, metered air enters the combustion chambers. The result is reduced piston ring wear, longer turbocharger life, stable compression, and consistent fuel economy. By investing in this premium filter, you directly lower your total cost of ownership through fewer repairs, extended oil change intervals, and improved reliability.

The AZ87351600100 air filter (ХИЙН ХУВААРЬЛАГЧ) is a direct replacement for the original equipment filter used in a wide variety of HOWO and Sitrak heavy‑duty trucks. It is compatible with HOWO‑7, HOWO T series, HOWO A7, Sitrak C7H, T7H, and M5G models, as well as many construction and mining machines that share the same filter housing. This filter is ideal for vehicles operating in dusty environments, such as mining haulers, dump trucks, concrete mixers, agricultural equipment, and long‑haul tractor‑trailers. Its robust design ensures reliable performance in both on‑road and off‑road applications, providing consistent engine protection regardless of the operating conditions.
The AZ87351600100 air filter is manufactured under stringent quality control to deliver consistent, reliable filtration performance. Unlike generic aftermarket filters that often use inferior media or weak end caps, this genuine HOWO filter features a proprietary micro‑fiber blend that balances high dust‑holding capacity with low airflow resistance. The pleats are heat‑stabilised to maintain their geometry under pulsing intake air, preventing collapse and ensuring even dust distribution. The polyurethane sealing rim is precision‑moulded to provide a leak‑proof fit in the housing, preventing unfiltered air from bypassing the media. Each filter is tested for burst strength, filtration efficiency, and pressure drop per ISO 5011, guaranteeing that it meets the same high standards as the original equipment. With its proven durability and performance, this filter is the top choice for professionals who demand the best for their engines.
Laboratory‑Certified Efficiency
Independently tested to capture ≥ 99.5% of particles down to 5 μm.
Moisture‑Repellent Media
Hydrophobic treatment prevents water absorption, maintaining filtration in humid or wet conditions.
Extended Service Life
High dust‑holding capacity (≥250 g) reduces replacement frequency and lowers maintenance costs.
Genuine OEM Guarantee
Manufactured to Sinotruk’s original design – guaranteed fit and function.
Replacing your AZ87351600100 air filter is a straightforward procedure that can be performed with minimal tools. Always park the vehicle on a level surface, engage the parking brake, and allow the engine to cool. Open the air cleaner housing, carefully remove the old filter, and inspect the housing interior for any debris or damage. Wipe the housing clean with a damp cloth, ensuring that the sealing surface is free from dirt and grease. Install the new filter, ensuring it seats fully and evenly in the housing. Secure the housing cover and verify that all clamps are tight. To maximise filter service life, inspect the air intake duct and pre‑cleaner regularly, and replace the filter more frequently in extremely dusty conditions – consult your vehicle’s maintenance schedule for specific intervals.
Choosing the AZ87351600100 genuine air filter is one of the most effective ways to protect your engine investment and optimise your fleet’s operating costs. Contaminated intake air is a leading cause of premature engine wear, leading to increased oil consumption, reduced compression, and eventual overhaul. By using a filter that meets OEM specifications, you ensure that your engine receives only clean, filtered air, which translates into better combustion, consistent power output, and lower fuel consumption. Fleet managers worldwide trust this filter to keep their HOWO and Sitrak trucks operating at peak performance, even in the harshest environments. With its proven reliability and long service life, it is the clear choice for those who value quality and dependability.
“We have been using the AZ87351600100 air filters across our fleet of 50 HOWO‑7 dump trucks operating in a limestone quarry. The filters consistently deliver outstanding dust protection, and we have seen a 20% reduction in engine wear‑related repairs. This is the only filter we trust for our equipment.”
The AZ87351600100 air filter is designed to fit a wide range of HOWO and Sitrak trucks, as well as other commercial vehicles equipped with the same air cleaner housing. It is a direct replacement for the original filter in HOWO‑7, HOWO T series, HOWO A7, Sitrak C7H, T7H, and M5G models, and is also compatible with many construction and mining equipment brands that use this common size. Always verify the OEM number AZ87351600100 on the packaging or part to ensure perfect fit and performance for your specific application.
Heavy‑duty trucks are routinely exposed to extreme environments – from scorching deserts with abrasive silica dust to freezing, wet climates with mud and slush. The AZ87351600100 air filter is engineered to deliver consistent performance across this entire range. Its synthetic‑blend media resists moisture absorption, preventing the filter from becoming waterlogged and restricting airflow. The robust pleat construction maintains its shape even under the high‑velocity airflow of a turbocharged diesel engine, while the polyurethane end seals remain flexible at sub‑zero temperatures, ensuring a leak‑free seal. This filter is designed to provide reliable engine protection for the full recommended service interval, reducing downtime and keeping your vehicle on the road.
Extreme Temperature Range
Operates reliably from -40°C to +80°C – no cracking or loss of efficiency.
Moisture & Humidity Resistant
Hydrophobic media prevents water absorption, maintaining filtration performance even in rain or snow.
Stable Airflow
Low pressure drop even at maximum engine load – ensures full power and throttle response.
Vibration & Impact Resistant
Sturdy construction withstands road shocks and engine vibration without pleat collapse or seal failure.
