Built with high-density synthetic media, it extends service life by 30% compared to standard filters, reducing replacement frequency. It meets ISO 9001 quality standards and carries CE certification, guaranteeing compliance with global automotive safety regulations. This filter protects engine components from wear, maintains optimal fuel efficiency, and supports consistent engine performance.
Product Advantage
1. Industry-Leading 99.5% Filtration Efficiency
This 1109112-D01 air filter uses high-density synthetic filtration media, capturing 99.5% of dust, pollen, and microscopic contaminants (≥0.3μm). This exceeds the global automotive air filter average (91%) by 8.5%, ensuring only clean air enters the engine. The multi-layered media structure avoids clogging quickly, maintaining consistent airflow even in dusty or harsh environments—critical for long-term engine health.
2. 35% Longer Service Life Than Standard Filters
Built with wear-resistant, temperature-resistant synthetic fibers (operating range: -40℃ to 120℃), the filter resists deformation and media breakdown. Test data shows it lasts up to 15,000 km under normal driving conditions, 35% longer than generic automotive air filters. This reduces replacement frequency for end-users, cutting their maintenance costs and enhancing user satisfaction.
3. Proven Engine Protection & Fuel Efficiency Boost
By blocking contaminants, the filter reduces engine component wear (e.g., cylinders, pistons) by 25%—verified by third-party automotive testing labs. It also optimizes air-fuel mixing: real-vehicle tests confirm it improves fuel efficiency by 4% compared to old or low-quality filters. For customers, this translates to extended engine lifespan and lower fuel expenses.
4. Dual Authoritative Certifications (ISO 9001 & CE)
As an ISO 9001 certified air filter, it adheres to strict quality control standards—from raw material inspection (100% batch testing) to final assembly (5-point performance checks). It also meets CE certification requirements for European and global markets, ensuring compliance with regional automotive safety regulations. This eliminates import risks for overseas buyers and builds trust in product reliability.
5. Precise Fit for Direct OEM Replacement
Using 3D scanning technology to replicate OEM dimensions, the filter features a tight-sealing rubber gasket that prevents unfiltered air leakage. It requires no modifications during installation, matching the fit of original filters. This makes it a hassle-free replacement option for repair shops and individual users, reducing installation time and fitment errors.

Product Uses
Here are specific application scenarios of Air filter:
1. High-Dust Environments (Mining Areas, Desert Peripheries)
In regions with heavy dust, its 99.5% filtration efficiency (for ≥0.3μm particles, SGS-tested) blocks fine debris from entering the engine. Compliant with ISO 16890 standards, it resists clogging 30% longer than generic filters, avoiding frequent replacements even in harsh, dusty conditions—critical for maintaining engine performance.
2. Urban Daily Commuting (Frequent Starts & Stops)
For daily city use, the filter reduces engine wear by 25% (third-party lab verified) by preventing contaminants from abrading components during frequent startups. It also boosts fuel efficiency by 4% (real-vehicle tested), cutting daily fuel costs for users who drive short, repeated trips.
3. Long-Haul Commercial Use (Continuous Operation)
Designed for vehicles running 8+ hours daily, it offers a 15,000km service life—35% longer than standard filters. Meeting ISO 9001 quality standards, it maintains stable airflow and filtration performance under prolonged use, reducing maintenance downtime for commercial fleets.
4. Extreme Climate Zones (Low-Temp Cold or High-Temp Heat)
With an operating temperature range of -40℃ to 120℃, its nitrile rubber (NBR) seal stays elastic in freezing or hot weather, preventing unfiltered air leaks. This adaptability ensures consistent engine protection, whether in cold northern regions or hot southern areas.
Product Operate Guide
Based on 15+ years of automotive filtration experience, follow these simple steps for safe, effective use: First, confirm the filter model matches 1109112-D01 (OEM code) to avoid fitment issues. Then, turn off the engine and wait 10 minutes for cooling (safety compliance). Remove the old filter, clean the filter housing, and install the new one—ensure its nitrile rubber seal fits tightly. Finally, check for air leaks; replace every 15,000km (SGS-verified service life) for optimal performance.
