The main function of the Carter oil filter is to filter the engine oil, improve its cleanliness and lubrication,. Supplying the crankshaft, connecting rod, camshaft, turbocharger, piston rings and other moving parts with clean engine oil plays a role in lubrication, cooling, and cleaning, thereby reducing engine wear, enabling them to perform at their best, and extending the life of these components.
