Replaces MAHLE PI 9315 DRG 40 oil filter

The Replaced MAHLE PI 9315 DRG 40 oil filter adopts a multi-layer gradient fiber structure, including a composite layer of glass fiber and synthetic material, which can intercept particle pollutants as small as 10um and achieve a filtration efficiency of over 98%. This design significantly reduces the risk of impurities in the fuel entering the high-pressure pump and fuel injectors, avoiding performance degradation or failure of precision components due to wear and tear. The internal of the filter element adopts a spiral flow guide structure to ensure minimal fuel flow resistance.
