PRODUCT DESCRIPTION
High-Density Filtration & Precision Fit
This air filter element (OE:11091001030DL01D) follows Dongfeng’s genuine standards, with high-density filter paper (traps fine dust) and a precision-molded orange plastic frame. The frame ensures a tight seal with Dongfeng DFAC’s filter housing, eliminating bypass gaps that let contaminants enter engines. Unlike aftermarket filter elements, its thick paper balances filtration efficiency and airflow, supporting consistent engine performance for long-haul transport.
Engine Wear Prevention & Aftermarket Filter Element Shortcomings
It is 100% compatible with Dongfeng DFAC’s air intake system (cross-check OE 11091001030DL01D for fitment). The filter element solves pain points: generic elements with low filtration (causing engine wear), flimsy frames (cracking during installation), and blocked airflow (reducing fuel efficiency). It cuts engine maintenance costs by 60% for fleets, extending component lifespan in dusty operating environments.
Factory-Certified Durability & Tested Performance
As an engine protection component, this filter element meets GB/T 14295-2008 air filter standards (third-party verified). It retains 95% airflow after 3000+ miles of use (fleet data) and the plastic frame resists -20℃ to 60℃ temperature extremes without warping. It is factory-calibrated to match Dongfeng DFAC’s air intake flow rates, avoiding performance loss.
