For about a nickle a day (over 5 years) I think I'll stick with the Filtermag. Cheap insurance if you ask me.

the chance of a sliver or shard getting past a quality oem filter element is extremely remote, 20(toyota filter) microns means very very fine dust so small in fact it would past right through the bearings along with the oil easily, and being a production engine it has not been blue printed to such fine bearing tolerances like race engines that such fine micron dust would harm it slim at best,
the particles most likely would have been from bearings/rings/bore and chain drive components "wearing in" then dripping down into the oil pan, from there they are sucked up by the oil pump and into the oil filter then on to the bearings and such, then cycle repeats again,
if its in your filter its already past through a major component, the oil pump, so why not try and prevent this?
(Some racing teams I know secure a necklace of magnets where the pickup is)
magnetic oil pan plugs work too as long as they are strong magnets being used, the cheaper Chinese made ones i've seen use low strength mags, and would only work when the engine has rested for a long time to let the particles sink down to it.
the most common engine failures involving bearings/oil is due more to loss of oil pressure, and worn oil pump gears/mating surfaces will drop oil pressures like a stone,(Honda vtec will not vtec with even a slightly worn oil pump) so buying $20 worth of neodymium magnets and sticking them close on the oil pan right where the oil pickup is and magnetizing pre oil pump is a far better idea,
Or better yet find a diesel oil filter that fits, they filter down to 10 microns. Far finer than most petrol engine oil filters,
story time: back in the good old days, "Japan made" black Toyota oil filters (mainly **GE corolla, Celica, supra etc) where so good it was rumered TRD filters of the same make where just repainted OEM ones, and there was quite a lot a evidance to support these claims, when a Toyota tech got wind that Toyota was going to outsource the filter manufacture, enthusiasts started hording filters, some guys even ordered them by the palette load,
