The significance of metal contamination of motor oil is a real concern. According to the white paper General Motors published, it stated that by using bypass filters you could get the micron size of metal contaminants down to 10 microns. Their testing proved that by this reduction in micron size alone, you could extend the life an engine by a whopping 70%.
By using Dimple strength magnets on these drain plugs you will be able to remove those micron particles!
Many GM products take this coarse thread plug, including Corvettes, Buick V6, Chevrolets, and Chevy trucks. It includes a 5/16″ diameter high temperature Neodymium magnet.
