Product Introduction
S1109160 High-efficiency Durable Optimized Air Filter for Lifan
Engineered for critical air intake protection, our S1109160 air filter delivers precision filtration for demanding engine environments. Crafted with a multi-layered non-woven media (cellulose-synthetic blend), it traps over 99% of airborne contaminants—dust, pollen, and particulates as fine as 5 microns—tested per ISO 5011 standards. The rigid, oil-resistant housing ensures structural integrity under high airflow, preventing bypass and maintaining optimal engine performance. Proven in rigorous cycling tests, it reduces engine wear by up to 30% compared to generic filters, extending service life. A cost-effective, OE-matching solution for consistent, long-term reliability.
Product Advantage
1. ISO 5011-Certified High-Efficiency Filtration
Our S1109160 uses a tri-layer cellulose-synthetic media rigorously tested to ISO 5011 standards, capturing over 99% of particles as small as 5 microns(dust, pollen, road debris). This precision minimizes engine abrasive wear by up to 30% vs. non-certified filters—critical for long-term engine health. For performance-focused buyers, it balances superior filtration with unrestricted airflow to maintain consistent power output.
2. Zero-Bypass Rugged Housing Design
Crafted from NBR-oil-resistant thermoplastic, the housing withstands -40°C to 120°C extremes and high airflow pressures. Unlike cheap paper filters, it eliminates “bypass”—unfiltered air leaking past worn seals—ensuring 100% of intake air is cleaned. Our cyclic stress tests confirm zero seal degradation after 500 hours of vibration, guaranteeing reliability for heavy-duty use.
3. CFD-Optimized Airflow for Peak Performance
Engineered via computational fluid dynamics (CFD), the pleat pattern maximizes filtration area while cutting airflow resistance by 12% vs. generic filters. This delivers 15% more clean airat the same pressure drop, boosting throttle response and fuel efficiency. Ideal for vehicles operating in dusty or urban environments where consistent airflow matters most.
4. 20% Longer Service Life = Lower Maintenance Costs
Field data from 10,000+ installed units shows our filter lasts up to 20% longerthan standard options—retaining integrity for 18,000+ miles (30,000+ km) under heavy use. This extends service intervals, reduces replacement frequency, and cuts downtime for end-users—adding value for distributors selling dependable aftermarket parts.
5. Rigorous Quality Checks for Unwavering Reliability
Every unit passes 12 quality tests, including a 1000-hour dust chamber simulation (replicating off-road conditions) and 300 kPa burst pressure checks. We source media from ISO 9001-certified suppliers, ensuring batch-to-batch consistency. For buyers prioritizing trust, this minimizes returns and builds loyalty with customers seeking hassle-free replacements.

Product Uses
Here are specific application scenarios of Air filter:
1. High-Dust Workplaces (Construction, Mining, Off-Road)
Ideal for vehicles in sandy, dusty environments, our filter traps ≥99% of 5μm particles (ISO 5011-tested)—including dirt, gravel, and airborne debris. Field data shows it reduces engine wear by up to 30% vs. generic options, preventing costly abrasive damage in daily high-stress use. Its rigid housing blocks dust infiltration, keeping engines running smoothly even in constant exposure to heavy particulates.
2. Urban Commuting & Stop-and-Go Traffic
Perfect for city driving, where frequent starts/stops suck in road dust and pollutants. Designed for longevity, it lasts up to 18,000 miles—validated by 10,000+ hours of real-world testing—cutting replacement frequency by 20% vs. standard filters. This saves users time/money on maintenance while maintaining clean airflow for consistent performance in busy urban areas.
3. Long-Haul Freight & Highway Driving
Built for distance, our CFD-optimized pleats maximize airflow (reducing restriction by 12%) and deliver 15% more clean air to the engine. This boosts throttle response and fuel efficiency on highways—critical for drivers covering thousands of miles. Its zero-bypass design ensures unwavering protection, reducing breakdown risks during long deliveries.
Product Operate Guide
For optimal results: 1) Clean the air intake of dirt/debris before installation to prevent foreign particle entry. 2) Align the filter’s NBR-sealed gasket with the housing—press firmly to ensure a leak-free fit (blocks ≥99% of 5μm particles, per ISO 5011). 3) Replace every 18,000 miles (or sooner in high-dust areas); do monthly visual checks for tears. This routine slashes engine wear by 30% vs. generic filters and maintains consistent airflow for peak performance.
