Product Advantage
1. Industry-Leading Filtration Efficiency with Authoritative Certification
As a high-efficiency air filter, it achieves ≥99.2% filtration precision (tested to ISO 5011 standards) to capture dust, pollen, and micro-debris as small as 3 microns. This exceeds the average 95% efficiency of generic filters, directly preventing abrasive damage to engine cylinders and pistons. Our R&D team has optimized the filter’s pleat density (28 pleats/inch) to balance airflow and filtration, ensuring no compromise between engine protection and power output.
2. Durable Material for 25% Longer Service Life
Crafted from imported composite filter paper (mixed with glass fiber and synthetic fibers) and reinforced with a galvanized steel frame, this long-lasting air filter resists high temperatures (up to 120℃) and humidity corrosion. Accelerated aging tests show it maintains stable performance for 15,000+ km, 25% longer than ordinary paper filters. The edge seal uses high-temperature-resistant EPDM rubber, which avoids air leakage caused by seal cracking— a common issue with low-quality filters.
3. OE-Grade Compatibility & 99.5% Fit Rate
Designed to meet OE specifications (matching the original air filter’s size, airflow resistance, and installation structure), this OE-grade air filter has passed 500+ fitment tests on compatible vehicle platforms, achieving a 99.5% perfect fit rate. It requires no modification during installation, and the snap-on design (same as OE) allows quick replacement in 5 minutes— ideal for both professional repair shops and DIY users. We’ve supplied this model to 20+ regional auto parts chains, with zero fitment complaint records in 2024.
4. Proven Performance: Reduces Engine Wear by 18%
Third-party vehicle tests confirm that using this air filter reduces engine internal wear by 18% compared to unqualified filters. It also improves fuel efficiency by 3% (tested under urban driving conditions) by ensuring consistent, clean airflow for optimal combustion. Backed by 5,000+ global buyer reviews, it holds a 98.6% customer satisfaction rate— with 82% of repeat buyers citing “reliable performance” as their key reason for repurchasing.
5. Strict Quality Control & 12-Month Warranty
Every 8104400XP24BA air filter undergoes 100% factory inspection (including airflow resistance, filtration efficiency, and structural integrity tests) before shipment. We provide a 12-month warranty— 6 months longer than the industry average— to cover any quality-related issues. Our quality management system is ISO 9001-certified, and each filter has a unique serial number for traceability, giving you full confidence in your purchase.

Product Uses
Here are specific application scenarios of Air filter:
1. Urban Daily Commuting
Ideal for vehicles used in dense urban areas, where intake air carries heavy exhaust particles, road dust, and pollen. Its ≥99.2% filtration efficiency (ISO 5011-tested) traps these contaminants, preventing engine wear. Data shows it reduces urban driving-related engine abrasion by 18%, keeping engines stable even during daily stop-and-go traffic.
2. Rural & Off-Road Driving
Perfect for vehicles navigating rural roads or light off-road terrain, which expose air filters to more sand, crop debris, and gravel dust. The composite filter paper (glass fiber + synthetic fiber) resists clogging, maintaining performance for 15,000+ km. Its 120℃ high-temperature resistance also handles heat from prolonged off-road engine loads.
3. Commercial Vehicle High-Frequency Use
Suits commercial vehicles (e.g., delivery, logistics) with high monthly mileage (3,000+ km). It ensures consistent airflow (≤120 Pa resistance @ 200 m³/h), boosting fuel efficiency by 3%—critical for cost-saving. Backed by a 24-month warranty, it minimizes downtime for commercial fleets, with 98% of fleet buyers reporting no filter-related breakdowns.
4. Extreme Climate Environments
Adapts to harsh climates: high-humidity areas (coastal regions) benefit from its corrosion-resistant galvanized steel frame (ASTM A653-certified); cold regions (-20℃ to 0℃) rely on its EPDM seal (ISO 815-tested) that won’t crack in low temps. It passed ISTA 3A storage tests, ensuring performance even after long shipments to extreme-climate regions.
5. Professional Repair Shop Aftermarket Replacements
A top choice for auto repair shops. Its 99.5% OE-fit rate eliminates installation errors, while the 5-minute quick-replace design speeds up service. Every unit undergoes 100% factory inspection, so shops face 0 quality complaint risks—20+ regional repair chains have made it their go-to replacement filter.
Product Operate Guide
1. Pre-Installation Preparation
First, confirm the part number (8104400XP24BA) matches your needs. Then, clean the air filter housing with a dry cloth—90% of post-installation engine dust issues come from leftover debris. Ensure hands are clean to avoid soiling the filter media; do not touch the filter paper directly.
2. Step-by-Step Installation
Open the air filter housing (follow your vehicle’s manual for clips/screws). Remove the old filter, then place the new one into the housing—align it with the edge seals (no gaps allowed). Close the housing and fasten clips/screws tightly. The whole process takes ~5 minutes, no special tools needed.
3. Replacement & Inspection Cycle
Replace the filter every 15,000–20,000 km (or 12 months, whichever comes first). For dusty/extreme climates, inspect monthly and shorten replacement to 10,000 km. A clogged filter (visible dust on media) can reduce fuel efficiency by 3%, so timely checks save costs.
4. Key Do’s & Don’ts
Do: Store unused filters in a dry, cool place (per ISTA 3A standards) to keep media effective.
Don’t: Wash or tap the filter to “reuse”—this damages the media, lowering filtration efficiency below ISO 5011’s 95% minimum.
