The SDHF air filter has many important functions: it can filter harmful particles such as dust, pollen, gravel, carbon black, and even water droplets from the air entering the engine, ensuring that only clean air enters the combustion chamber. In addition, the SDHF air filter also prevents damage to electronic components such as high-precision sensors (air flow meters) caused by various methods. The SDHF air filter also has other important functions: reducing intake noise, balancing air flow to the air flow meter, and sealing adjacent components.










SDHF adheres to years of production experience and consistently produces high-quality filters. According to the needs of each vehicle model, the selection of materials varies. With the support of a large amount of laboratory data, we can have a more intuitive understanding of the needs of each vehicle model and achieve a clear understanding. Advanced production equipment can make our products comparable to host products. Excellent technology and reasonable design have kept us at the forefront of the industry.
