Hi Shorty that sounds like a plan to me, i just so happen to have a pair of those laying around that i stripped out of a hard drive. May i just ask where you place yours ie: down side's or on the bottom of said filter cartridge and do you use both magnets or just the one ?There's another option if you can get a hold of some old computer hard drives. I've canibalized the neodynium magnets (don't know if that's spelled correctly) and slapped one on the outside of the oil filter. Or you can buy some on the net. Been doing this for 5 years now. You just have to remember to put the magnet on the new filter when you do an oil change.
