Compliant with ISO 5011 standards, this filter ensures consistent airflow—reducing fuel consumption by up to 3% while boosting engine efficiency. Its reinforced frame enhances durability, supporting a service life of up to 5,000 km under normal driving conditions.
Designed for easy installation, it meets strict OE specifications, making it a reliable choice for maintaining long-term engine performance.
Product Advantage
1. Industry-Leading 99.8% Filtration Precision with High-Density Synthetic Media
This high-performance air filter adopts a 3-layer synthetic fiber structure, which traps 99.8% of dust, sand, pollen, and tiny debris (as small as 0.3 microns). It exceeds the average filtration rate of conventional paper filters by 12%, effectively preventing abrasive particles from entering the engine and reducing internal wear by up to 40%. The media also complies with ISO 5011 standards, ensuring consistent filtration performance in both dry and humid environments.
2. Reinforced Frame for 5,000+ km Long Service Life
Unlike ordinary filters with fragile cardboard frames, the T11-1109111 uses a reinforced PP plastic frame with anti-deformation technology. This design enhances structural stability by 35%, resisting cracking or warping even under extreme temperature changes (-40℃ to 120℃). Under normal driving conditions, it maintains optimal performance for 5,000+ km—1.5 times longer than the average service life of entry-level premium air filter for engine protection.
3. Optimized Airflow Design to Boost Fuel Efficiency by 3%
We’ve conducted 200+ airflow simulation tests to refine the filter’s pleat density and shape. The 180° uniform pleat distribution increases effective air intake area by 20%, reducing airflow resistance by 15%. This ensures the engine receives sufficient clean air, improving combustion efficiency and cutting fuel consumption by up to 3%. It also helps maintain stable power output, avoiding performance drops caused by clogged filters.
4. OE-Spec Fitment for Tool-Free, 2-Minute Installation
The T11-1109111 is manufactured to match original equipment (OE) dimensions with a tolerance of ±0.1mm, ensuring a perfect fit with the engine’s air intake system. It requires no additional modifications or special tools—users can complete installation in just 2 minutes by following basic steps. This not only saves maintenance time but also eliminates the risk of air leakage (a common issue with ill-fitting filters), which could lead to unfiltered air entering the engine.
5. ISO 9001 & SGS Certifications for Guaranteed Quality
Our production process is certified by ISO 9001, and each batch of T11-1109111 filters undergoes SGS testing for filtration efficiency, frame durability, and chemical resistance. We also provide a 12-month quality warranty—if the filter fails due to material or manufacturing defects within the warranty period, we offer free replacement. This commitment makes it a trusted choice for customers seeking ISO 5011 certified air filter with reliable after-sales support.

Product Uses
Here are specific application scenarios of Air filter:
1. Daily Urban Commuting
Ideal for frequent stop-and-go urban driving, where air is filled with exhaust particles, road dust, and pollen. Its 99.8% filtration efficiency (for 0.3μm particles, ISO 5011 tested) traps these contaminants, preventing engine wear by up to 40%. It maintains stable performance even in heavy traffic, avoiding airflow blockages that cause power drops.
2. Long-Distance Highway Driving
Highway driving demands consistent airflow for fuel efficiency. The filter’s optimized pleat design (32±2 pleats) boosts air intake area by 20%, cutting airflow resistance by 15%. This ensures the engine gets sufficient clean air, reducing fuel consumption by up to 3% during long trips and supporting reliable performance over 5,000+ km.
3. Dusty or Humid Environments
Perfect for regions with sand, dust storms, or high humidity. Its 3-layer synthetic fiber media resists water absorption (tested in 95% RH non-condensing conditions) and traps 99.8% of dust. The reinforced PP frame also withstands temperature swings (-40℃ to 120℃), preventing deformation that leads to air leakage.
4. Commercial Vehicle High-Frequency Use
Suitable for light commercial vehicles with daily high mileage (e.g., delivery vans). Its dust holding capacity (≥120g) and 1.5x longer service life than ordinary filters reduce replacement frequency. The SGS-certified durability ensures it handles repeated engine starts/stops without performance degradation.
5. Routine Maintenance Replacement
Designed as a direct OE-spec replacement (tolerance ±0.1mm) for worn filters. With tool-free, 2-minute installation, it’s easy for both professionals and DIY users. Replacing old filters with it restores engine efficiency—tests show it can recover up to 5% of lost power caused by clogged, outdated filters.
Product Operate Guide
Locate the engine’s air intake box and open its clips/screws.
Remove the old filter, wipe dust from the box (to avoid residue mixing), and check for damage.
Insert the T11-1109111 filter—its OE-spec design (±0.1mm tolerance) ensures a perfect fit.
Close the box tightly; confirm the nitrile rubber seal is intact to prevent unfiltered air leakage.
Replace every 5,000 km (or as needed in dusty areas) for optimal engine performance.
