RE: Magnets on Oil Filters

["Duff, Ian" <iduff@charter.com>]

What an excellent idea!
How much of the magnetic field passes thru the (presumably) steel filter
housing?
Have you ever checked the old filter for particles?
Can you supply more info on how to get the magnet you use?
How do you keep the magnet on the filter (its own magnetism, or some
external help)?
