With over 40 different looks (and growing) it is easy to find one that is unique for you.
Most importantly, the HiFlow 587 does not feed hot, dirty, oily air back into your engine.
By venting to the atmosphere you will get more performance, AND your engine will last longer. (engines like cool dry air, not dirty hot oily air)
Putting dirty oily air back into your intake will build up carbon, reducing engine life. Also, down the road you may end up with pinging as the carbon builds up.

Interesting, I thought all of them vented back to the intake. Could you elaborate on how the 587 system vents the oil to the atmosphere?

More and more of the aftermarket A/C's are pushing the dirty hot oily air into the intake because of the EPA. Putting dirty air into the intake sort of nullifies the whole idea of having an air cleaner...it is relatively new to Harleys.
We have two external systems-
1. OUTLAW Breather Bolts, you can read about them HERE, and there is a pic below.
2. Traditional Hose & Filter style breather, you can read about them HERE, and there is a pic below. (This is how millions upon millions of HD's have run for decades until the EPA said they knew better and to bypass the filter and put dirty air straight into the engine)
Yes, am going to reroute that engine breather to atmosphere as one of my first projects when I get my "new" 2007 FLHP next week.
Was mentioning what a p*ss poor design this was with no filter/oil gatherer on another post and was getting all kinds of flack like I was nuts or something. :-)
Those breather head bolts with the little screens look interesting but wouldn't you have oil dripping down the cooling fins at times?
