I must say that HD did somethig right when they designed it. I would recommend it.

I don't know of any others.
Pushing blow-by back into the air cleaner is counter productive to performance. What comes out of the breathers is primarily exhaust and oil.
It is also hot. Engines perform better with cool dry air and gas...not hot oily air and gas.
Additionally the exhaust gas has a lower oxygen content, displacing oxygen on each combustion stroke. Another performance robber.
Oil will build up carbon deposits on the pistons, leading to pinging/tuning problems down the road.
It's just a bad idea...the only upside is you make the EPA happy.

Just to chime in, TBR offers an intake system for the Dyna that has a dual feature, screw on end-cap that utilizes the custom K&N filter or screw on v-stack that inducts air straight in to the motor (if you need some extra hourses). Comp-V High-Flow Intake System:
