Most quality filters have a bypass built into them. So the factory bypass is really redundent. Most filter sights say whether a filter number has a built in bypass. Or cut apart the planed filter you will use and if it has a means for the filter media to move down in the housing like a spring or a piece of spring steel under it . It will bypass if the filter clogs or is out ran by pressure. But if you allow the engine to warm up and change the oil regularly the filter bypass really never does anything. So plug it buy a filter with a built in bypass and forget about it. Rod
