117010-E9300 OEM Diesel Fuel Filter The 1117010-E9300 fuel fine filter is an original standard aftermarket replacement filter specially developed for Dongfeng Dragon DDi11 series national six diesel engines, widely matched to Dongfeng heavy-duty commercial trucks. During long-distance transportation and harsh working conditions, diesel fuel will inevitably mix with water, rust particles, sediment, dust and tiny metal impurities, which will cause injector blockage, fuel pump wear, insufficient engine power, unstable idle speed, difficult cold start and increased fuel consumption seriously. This filter adopts advanced multi-layer gradient filtration technology to efficiently trap solid contaminants and separate tiny moisture inside diesel fuel, delivering ultra-clean fuel to the engine fuel system steadily. It effectively protects precision fuel injection components, stabilizes engine dynamic performance, reduces failure rate obviously, and supports long service life up to 100,000 kilometers under normal driving conditions. Produced under strict ISO automotive manufacturing standards, it maintains stable filtration efficiency under high pressure and wide temperature fluctuation, becoming an essential reliable protective part for daily logistics transportation and heavy-load engineering operation of medium and heavy trucks.
Product Material Description:
Filter Medium: High-density imported composite glass fiber filter paper with gradient pleated structure, featuring high dirt holding capacity and stable filtration precision;
Outer Housing: Thickened cold-rolled steel shell with full anti-rust electrophoretic coating, resistant to diesel corrosion, external collision and scratch damage;
