The inside of the oil filter creates a strong high-temperature resistant magnetic field. During high-temperature and high-speed operation, engines inevitably produce metal particles. Iron particles are very hard; if they circulate with the oil, they can enter critical engine components and increase wear. This filter uses magnetic technology to capture iron particles from the oil.Adsorption power: Niobium alloy magnetic steel generates a strong magnetic field that firmly captures small iron filings produced by the engine, preventing them from re-entering the system.Extend engine life: Oil filtered through this magnetic system contains fewer impurities, resulting in smoother performance and reduced friction. Engines operate more quietly and efficiently.Purifies oil: Magnetic filtration captures iron particles and other harmful solid contaminants within the oil filter. Even beyond regular maintenance intervals, oil remains cleaner and maintains better flow.Reduce consumption and support environmental efficiency: By reducing engine wear by up to 90% and cutting wear debris by over three times, this product helps maintain engine performance while supporting eco-friendly operation.Color: Blue Material: High temperature resistant, environmentally friendly silicone Product length: 23cm Package Contents: 1 x Magnetizer Note: Only the items listed above are included.
