Probably a manufacturing consideration and not an oil flow concern...the oil will flow between the pleats and down the spiral groove in the center tube.quote:

Looking at the center tube--do my eyes deceive me-- do the holes ( slots) in the center tube not extend from top to bottom of the element?
It looks like the center tube is "solid" towards the top and bottom and only the very middle has holes....is this correct?
That would be my take on it too. If you add up the inlet holes on the base plate you don't get much in terms of total area ..there's not much need for the center tube outlet to have all that much either.quote:

No, what you see is the 3/8" (+-) seam. The tube spirals bottom to top. If you look close you can see an opening at the top edge of cut-open.quote:
