This engine oil filter removes particulate and contaminants from the engine lubrication circuit before oil reaches the main bearings and turbocharger. It is a full-flow spin-on element that mounts on the engine block and receives unfiltered oil directly from the oil pump. A clogged filter restricts oil flow, which can cause the bypass valve to open and allow unfiltered oil to circulate, accelerating wear on bearing surfaces. This original component uses the correct bypass-valve cracking pressure and seal geometry for the housing, ensuring the filter remains sealed under operating pressure and vibration. On replacement, clean the mounting surface and pre-fill the filter with oil before installation.
