Iron Grip
Brak Check, (800) 642-6364, has developed the Bear Trap, a foam jacket containing magnetic buttons that help your oil filter remove wear-causing iron particles. It wraps around your spin-on filter, held in place by its own magnets. These also magnetize the steel filter case so it attracts and holds between 75% and 80% of suspended iron particles from 25 to 5 microns, according to the maker.
