What air cleaner?

There are a few things that are different between DK Custom Outlaw air cleaners and most every other Stage 1 air cleaner.
The Outlaws do not feed hot, dirty, oily air from the crankcase back into the engine. Almost every other Stage 1 A/C being made does that.
Internal combustion engines are made to run on gas and air, feeding dirty oil into the engine reduces performances.
Engines also run better the cooler the air is. By Not pushing that hot crankcase air into the engine like most other A/C's do, the DK Outlaw A/C's further increase performance.
Besides a performance benefit, there is also another benefit. Reduced carbon build-up on the pistons.
There are hundreds of people just on this forum every year that make a post about how they have not done anything different, but after x number of months their bike has started pinging.
Almost every time this is because carbon from that dirty oily crankcase air has built up on their pistons. This reduces engine longevity and also will probably require that they spend more time/money retuning the bike to get rid of the pinging/pre-detonation.
Besides the above benefits, we use lower-profile K&N filters that result in more leg room from the A/C not pushing your right leg out from the bike.
Lots of design options too.

All engines have to vent the crankcase pressure somewhere. The EPA does not want that dirty oily air going into the atmosphere, so they make MFG vent them back into the engine.
We have two different styles that both vent into the atmosphere.
Breather Bolts -
or
The Traditional Hose and filter system -
See details on both styles HERE

So on those breather bolts....dont you get some oil condensation and dripping down the side of your engine with that method? I like the idea tho.

One of my bikes still has the stock filter, and that's probably what I'll stay with.

I have the DK Customs filter on my bike. I have never had oil drip on the side of my engine. I think that may only happen if you let your bike sit for an extended period of time without starting it. If you do, that oil would go into your stock filter anyway. I love the DK air filter. Go for it.

I have a v&h drak black on my wide glide now and have been thinking about replacing with a dk. Is that a hard switch to make for a not so mechanically inclined individual such as myself? And will I need a retune?

No problem.

How can your AC do that and other companies have to play by the rules?
Or is abiding by the EPA regulations optional?
I'm leaning towards a Cobra Powerflow A/C they just look cool!

however even with the strictest emmisions laws in the country CHP wont write you a ticket unless your belching smoke/fire or silly loud. CARB however does go after dealerships/shops that knowingly install parts that are not CARB certified.
the way companies get around that is the products get marked for competition/off road/show use absolving the mfg from liability and passing it on to the end user.
that being said. my 587 should show up tommorow.
