The oil filter, also known as the oil strainer, removes impurities such as dust, metal particles, carbon deposits, and soot particles from the oil to protect the engine.
Oil filters are divided into full-flow and bypass types. Full-flow filters are connected in series between the oil pump and the main oil gallery, filtering all the lubricating oil that enters the main oil gallery. Bypass filters are connected in parallel with the main oil gallery, filtering only part of the lubricating oil pumped by the oil pump.

Material: High-precision, low-cost (commonly used in oil and air filters).
Using imported high-quality filter materials effectively protects the engine, reduces wear and tear, and extends its lifespan.
Automatically activates when the filter element is clogged, ensuring that the oil can still flow even without filtration (to prevent engine oil starvation).
The oil filter is a crucial component in the engine lubrication system. Its core function is to filter impurities, metal particles, sludge, and other contaminants from the oil, ensuring the cleanliness of the oil and thereby protecting the normal operation of the engine's various parts.
