This engine oil filter removes particulate contamination from the lubricating oil before it circulates through the engine’s bearing surfaces and oil galleries. It is a full-flow spin-on type, mounted on the engine block where it receives oil directly from the pump. A clogged filter restricts oil flow, which can cause the bypass valve to open and allow unfiltered oil to reach critical components, accelerating wear. Mann-Filter manufactures this element to match the original housing thread and seal surface geometry, ensuring the bypass valve seats correctly and the gasket seals without leakage. On replacement, clean the mounting surface and pre-fill the filter with clean oil before installation.
