Myself I would eliminate the air ducting if for nothing else so you can figure out why the engine light is coming on. After I figured that out then I'd be looking at do I want other mods. You are the first person I've ever heard has a engine light and no code. This is why I would figure that out first before throwing money at more then just the air filters. Something is loose that sends the code and is corrected before it's a permanent code. At its age it could just be a sparatic vacuum leak, loose low tension leads on a coil. I'd run that down after you do the filter mod.
Just my 2.5 cents worth.
Tell us more about it. You say its a 07 Classic is it a tourer model or just the Classic? Is the motor silver or black? Pictures are a lot of help if you're not sure. From your avatar I think she is a Classic Tourer correct me if I'm wrong. And get used to me being wrong

BEWARE... LONG POST AHEAD....
07 Classic Touring purchased with 7k miles last year and currently 15k on the meter. From my understanding a tourer of this year is just a normal classic with some accessories like bags, floorboards, and the such added on.
I have messed with the electrical a tad through the following: Installed LED headlights because the stock illumination was pretty rough. Had these lights on for months before the check engine light issue so I am doubtful it's related.
Installed tender connector to battery for easy plugins. Also added underglows, 100watt amp and 2 speakers to battery. To verify I didn't have a wire rubbing or voltage leeching from these to the main harness I disconnected them from battery but the light stuck around.
Only other mechanical type mod was a k&n under seat filter. I have updated tune but that wasn't till after the light issue started.
From what I remember the light first came on last fall when I accidentally killed it (thought it was in neutral and it wasn't). After the normal shake and "clunk" the light came on. After that it was very sporatic, usually only comming on during humid or cool evenings. Living where I do in the midwest USA, I would leave the house and it would be 80F 30% humidity. Returning home after work it might be 45F and 80% humidity so I started think the ecu was just freaking out because of the sudden environment changes.
So far I have traced wires for rubs, checked connectors, replaced plugs for good measure, reaseated coil pickups (they seemed loose so I tightened), and opened the housing to check for corrosion. I started to do the iscv process but read about it after I got the plenum back together. I'm going to wait until my K&Ns get here to do it because I have to take the air assembly off again anyway. I plan on fogging for vacuum leaks at this time as well. There is very slight surging on idle, like 20 RPM but I'm not sure if that's normal for this bike.
Emailed Paul from viking exhaust and told him to shut up and take my money, will be ordering his chrome complete 3-1 kit after finishing this post.
