High quality filter media, good packaging and fast delivrey. Oil filter is located in the lubrication system in the engine. It is the key component in safeguarding a vehicle's engine It's used to lubricate elements, reduce wear and balance engine. Automotive oil filters also protect the engine by preserving a tiny fraction of oil when the car engine is turned off. All of these are made possible through a device called the anti-drain back valve. Most of spin-on oil filters have both anti-drain back valves and bypass valves. An engine at a standstill enables oil to drain into the bottom of the engine, thus leaving the moving parts at the top of the engine without the proper lubrication it needs when the car has to be started again. Fortunately, proper lubrication is easily restored as the small amount of oil retained by the oil filter will quickly circulate into the top of the engine immediately after the car is started. They are one part of our competitive product lines. We provide both spin-on oil filters and oil filter cartridges.
