Just so you're aware of what bmwtechguy is saying. The hydraulic filters are 1-12 thread. They'll run you about $8 from NAPA. That's the common thread for just about all low pressure hydraulic filters. They're typically the size of an FL1A. You might find the lifetime supply on ebay for cheap ..but generally speaking, they're about 2-4 times as expensive as cheaper automotive filter ..and a little more than a Purolator PureONE. The mount will cost you a bit more (also available from NAPA - Jeg's, Summit).
As he also said, you could simplify the installation with a Magnefine. That will only require a couple of hose clamps. In conjunction with a bypass filter, I think it would last years (as would the hydraulic or other full flow fitler).
After the bypass filter has been in there for a while, the full flow will have virtually no loading except for the random larger stray particle. All the junk that suspended should be trapped. Those who have MG's or Frantz (toilet paper filters) get to see the cleaning process when they change out the rolls.
