How often do you guys clean and re-oil your Green Filter's?

According to their website, its recommended every 30k miles, however that is all dependent on environment conditions (dusty/not so clean air). Im just wondering so I'm prepared too (probably going to do it early at 15-20k) buy the oil and cleaner kit. Supposedly "supposedly" green filters aren't the greatest at filtration to begin with (trigger the oil/cloth war) however I want to sort of combat that by doing it early.

I've found two different kits on Amazon so I'll have to figure out which is different and needed for our particular filter.

Also planning on ordering the Focus RS air box here pretty soon, anyone have any input on those on the intake with stock filter and aftermarket? YouTube didn't yield much results, I guess if not I can always test myself and post a video but I'm going to take a wild guess and say it sounds nearly identical to the stock ST airbox with the lid off.

Actually just got done cleaning my Cobb filter about an hour ago. Simply ordered their cleaning kit online (about $15) and used that. Sprayed it down with the green solution then rinsed it and let it dry. Placed some paper towels inside the filter to prevent any extra oil getting inside then re-oiled it and let it sit some more then reassembled.

RS airbox has a more open top cover, but is sealed by a rubber lip all around the "open" top. I doubt you'll hear a difference and I personally wouldn't spend the money on it. Looks cool though.

Mostly would get it for the looks, not that I ever look much underneath. I just wanna do random small things to the car and I'd rather not spend money on a full blown aftermarket intake because I really don't find any attractive, especially at 200+.

Every 6 months, which ends up being about 3,500 miles for me.

30k miles seems extreme considering Cobb's own filter cleaner recommends 3-5k.

I change and clean mine when I change my wheels. I have two filters, one nasty looking one that I'm using for winter, and the nice clean green one that I use for summer. So when I swap my setup I swap filters out.

My plan was to clean and oil with every 5k oil change.

As for the RS air box, I ordered one last week and should be getting it in a day or two. I actually wanted it for the sound, since I didn't like the idea of running without the stock airbox lid, and wasn't interested in buying a full CAI.

This is gonna sound snobby but just replace the filter...extra oil can get on the air flow sensor then you have to clean that, not ideal
