In an automobile, the apparatus is interposed between the normally provided spin on oil filter and its point of attachment to the engine block. The device is similar in size and shape to a flat cylinder, possessing an internal chamber filled with numerous discrete magnets, a ring magnet with multiple poles, a magnetic grid or sponge, or other filter media. The cylinder is designed with a number of radially disposed holes which allow the pressurized lubricant fluid coming from the normally provided engine oil pump to pass through the puck and into the spin on filter and into the engine. This is the main flow. The radially disposed holes collectively act as an orifice restriction to the flow of oil. A method is suggested to achieve pressure differential between the two sides of the cylinder due to the orifice restriction. A sealed hollow chamber or duct is provided inside the cylinder. Multiple magnets, or other filter media, are placed inside the sealed chamber. Next, diametrically opposed sets of control orifices, carefully sized with predetermined numbers and diameters, are made on the engine side and on the filter side. The orifices in the upstream side and on the downstream side, effectively become the intake and exhaust of a self-contained magnetic bypass filter respectively. The puck is easily secured by means of a threaded nipple. A set of fins is placed around the cylinder to include the additional function of bypass flow cooling.
