Clean air filtration directly impacts combustion efficiency and engine power output. The WG9725190190- 001 WG9725190190-002 filters prevent abrasive wear on cylinder walls and piston rings.
Reduced contaminant ingress extends turbocharger life and maintains boost pressure. Proper filtration minimizes oil contamination and extends intervals between oil changes.
Maintaining optimal air-fuel ratio improves fuel economy and reduces emissions. These filters protect expensive engine components, reducing overall maintenance costs.
Always replace both WG9725190190- 001 WG9725190190-002 filters as a complete set. Inspect the air filter housing for damage or debris before installation.
Ensure proper seating of gaskets and secure all housing clamps according to torque specifications. Never run the engine with damaged or improperly installed air filters.
Reset the service indicator or record the replacement mileage for maintenance tracking. Check for air leaks around the housing after installation to ensure system integrity.
Follow SINOTRUK’s recommended service intervals, but adjust based on operating conditions. Severe dust environments require more frequent filter changes.
Reduced engine power, especially during acceleration or under load, indicates restriction. Black smoke from exhaust can signal rich fuel mixture due to inadequate airflow.
Unusual turbocharger whine or whistle may indicate air intake restriction. The restriction gauge (if equipped) showing red or excessive vacuum reading.
Visible dust or dirt bypassing the filter media or on the clean air side. Increased fuel consumption without other apparent causes often points to clogged filters.
This filter set is designed for various SINOTRUK Howo truck series with specific air intake systems. Compatibility includes Howo A7, Howo T7, and several Howo ZZ chassis.
The WG9725190190- 001 WG9725190190-002 filters are used in conjunction with specific air filter housings. Always verify both part numbers against your vehicle’s air intake configuration.
These filters are essential for dump trucks, tractors, and mixers operating in dusty environments. Correct application ensures proper fit and optimal filtration performance.
Each WG9725190190- 001 WG9725190190-002 filter undergoes rigorous quality testing. This includes efficiency testing, burst strength evaluation, and dust holding capacity measurements.
