I took some pictures to compare the SE filter vs the stock.. (Just found them on my phone today and figured I'd post them so anyone considering the filter could see the difference). The SE filter is noticeably larger, so it must flow more air. Hopefully it's the 36% more that they claim. Here are some shots from the same side angle and some from the intake end and one of the filter in place.

the increased filter area AND the filter media being more porous than the OEM paper is the reason .. I have never been a K&N oiled cotton filter fan because along with more air passing through, there's more airborne contaminants being ingested ... but unlike the ones flow directly into the throttle body with velocity, this design with the backing stops that from happening so dirt is less intrusive, in theory anyway ..or so it would seem ... either way my airbox has been surprisingly clean and much better than previous ones so I'm calling it a win using the K&N for my application
Just curious. Does a filter element change require a tune AKA Stage 1 program to the ECM ?
this particular filter does not, it's marketed as a direct replacement for the OEM .. typically it's when you upgrade to the AC kits they require the recalibration...to the following question about paper filters in rain..they can get water logged and not breathe as well when that happens ... it's best to remember your rain sock regardless of the filter media, they are provided for a reason but for mild rain not usually a problem..it's when those gulley washers crop up they can be

Thanks mjwebb. My thinking is that an oiled filter would have a slightly higher tolerance for rain than paper, but yeah... the sock is probably your best friend either way.
What if you add this filter and slip-ons, still no tune required?
required according to HD, and what I have always done, most recently last week and it brings it all together properly for a slight but noticeable improvement
I had a K&N filter and a set of SE Street Cannons on my '22 107 Road King. I never bothered with a tune. It ran OK for over a year but I never noticed even the slightest difference in performance. It just sounded better with the Street Cannons.
I've since switched the Cannons over to the Road Glide and I added the SE K&N filter for the 117. This time I did a tune with an SE Pro Street Tuner. All I've done so far was put in a base tune,telling it I have the SE mufflers and SE intake. Like with my Road King, I didn't expect any change, but it was there. It actually surprised me. I didn't have to look for it. The motor definitely felt a bit more perky with the tune.
If it ever stops raining I'm going to go for a ride and record some tables so I can apply them and fine tune it further.
