not as extremely functional as four baffled chrome breathers though... I'll take 4 times the crank case breathing at 1/5th the cost

Myself...
I'd like to hear what you base this fact on?.Have you done a pressure test with your exiting crankcase pressure to verify that these are not as good as the old drill and shove them in chromie breathers?.I am guessing that you never looked at one of these close up to see the inners and how much area they have for pressure ventilation,plus the added benefit of making sure the oil stays in the motor and not out through the push in breathers.Hmmmm.......
