The main function of the Carter oil filter is to filter the engine oil inside the engine, improving its cleanliness and lubrication. Clean engine oil is supplied to the crankshaft, connecting rod, camshaft, turbocharger, piston rings and other moving pairs to play a role in lubrication, cooling and cleaning, thereby reducing the wear of the engine, enabling it to function at its best and extending the service life of these components.

Just like the blood circulation system of the heart, the oil in the oil pump is also constantly circulating. During this process, many unexpected impurities are often produced, and such unclean substances need to be filtered out by the oil filter element.
