What are the qualities of a good oil filter? One, it should have an excellent filtering ability. Two, oil flow toward the engine should be unrestricted. Three, it should withstand the pressure from the oil pump. Otherwise, the engine will not receive its needed amount of oil for lubrication. The oil filter may also be damaged due to friction. To ensure good oil filtration under your car hood, go for a Magnafilter oil filter. A magnetic type of filter, this Magnafilter product keeps oil cleaner for a long time and extends the life of the engine to as much as six times compared to average filters. And, it does both of these while improving fuel economy. Designed for easy installation, the Magnafilter oil filter can be easily mounted without affecting your vehicle's factory warranty in any way. To ensure that you enjoy the filter's longer-lasting service, perform periodic oil change and regularly inspect other filter parts like the oil filter mount or oil filter base to ensure proper filter mounting.
