Air Intake Upgrades
I have a 2017 Street Glide Sp. And I have the OG air filter on there and it is starting to drive me nuts. Every day that I ride I have to clean off the heat shield, passenger peg, side cover and front of the hard bag of oil spill over. I have taken the filter off and given it a good Ole cleaning and removed the breather tubes within the filter housing and they arent clogged. But because the stock intake has those tubes at the bottom of the intake the over flow of the oil dribbles out into the air filter.
I am looking to upgrade to something aftermarket and wanted to see if anyone could give me some recommendations based on what they have. Not looking for something super expensive or high performance, just something that looks nice and doesnt leak oil when I ride.
Thanks for the help yall.

Well I had the oil changed by the stealership, and that was months ago. So if it was over filled I would think that would only last a short period of time. But then again I could be totally wrong!

Changing air intakes is not going to solve the problem. How many miles on the bike? Any performance modifications? Over filling would do it and just because the dealership did the oil change certainly doesn't mean it was not over filled. Is this the first oil change? Is this a new issue?
Venting the head breathers to the atmosphere will vent the oil somewhere else but it sounds like any external venting system will need a catch can. Check out DK Customs; they offer a variety of external venting set ups. I don't know how much oil is gettng puked out but, if a lot, further investigation may be necessary to figure out why.

I know the the breathers come in at the bottom of the intake so when the oil drips it just slides down and into the filter. I know that Vance and Hines makes one where the breathers come in at the top which makes the oil pass through the air flow and has less of a chance to hit the filter. Only issue I have with that is that I don't want to spend $300 on an air filter.

I'd pull the crank position sensor and measure how much oil comes out of there and then remove the sump plug and measure that oil
Early M8's had issues with the oil pump scavenging all the oil it needed to, so your crank ends up swimming in a bunch of oil that shouldn't be in the sump, crank rotating splashes it all over, now there is more oil suspended in the crankcase gasses than there should be

I never let anyone do fluid changes on my bikes. I do them myself. When you take your bike to a dealer for service, the work is assigned to the lowest paid,lowest skilled tech because it is easy to do. So you most likely get over/under filled because no one cares and no one checks.
So anyone who doesn't check fluid levels after service is asking for problems down the road.

There is roughly 7500 miles on the bike. Only thing that was added was some slip ons but that was done before I bought it. And I agree that anyone can over fill it, even the stealership! The amount of oil really isn't a massive amount, but enough that I have to clean it off the bike whenever I ride.
I know the the breathers come in at the bottom of the intake so when the oil drips it just slides down and into the filter.

Visit the DK Customs website; some good information and solutions there.
