your oil filter preference

Cool! Flow is only effected by media filter area decreasing due to plugging (the magnet has

no effect on the distribution of non ferrous particles to the media), Thus resulting in higher fluid velocity through the remaining media.

In laminar flow surface friction has minimal to no effect on turbulence. The Filter mag

attaches the particles to the side of the canister and has marginal effect on restricting

flow (from friction) along that side of the canister, unless/until the magnet captured

enough particles to restrict flow in that area. This would then require the dual filters to

spread out the captured particles over a wider area. However in my opinion,

going back to oil change interval, for this to happen you would have to have pretty

severe engine damage occurring to have this quantity of ferrous circulating debris. Hope this answers the

question.
