ok, so looking around I'm starting to get worried...

What is that black tub connected to the valve cover(on the left side)? where does it go to? I havn't had time to look around under the hood in a while...

It should run to the air cleaner

what is that in relation to the airbox?

I noticed some people attach it to their aftermarket intakes... if you take a look in my gallery I have an injen intake, but there is no where to put it. I hope everything is ok...

It looks as if that intake uses the factory lower air box? If it does, it should still go where it was factory, in the side of the lower airbox.

ok, it does still use the factory lower half of the airbox, but shouldn't it have some sort of filter?

It has a small foam insert in the box, if its not there, all you need is a Motorcraft #FA1693

ok, I never touched it so it should be fine. my intake is a PITA to get on/off so I'll have to wait untill I have alot of time to check.

It goes to your factory airbox, and most aftermarket air intakes have a spot for them too. The good news; it's not important apparently. I removed my whole airbox assembly to install my intake and needed a tamper-proof torx bit so I put it all back to gether. Well when I removed it again to install the intake, I had forgotten to re-install the stupid thing, for who knows how long? If you're not using it (let me know how that injen is by the way!) just close off the end or something and you should be fine.

It shares the airflow with the engine to allow the head to breathe. I broke the orignal tube once and had to seal it off with a piece of electrical tape, and my car ran like crap. If it's left exposed, it acts like a vacuum because of the moving internals, and it will suck all kinds of nasty things into your head.

After I broke the original tube and before I had my AEM, I went to Advance Auto Parts and bought a Mr. Gasket Oil Breather for $10. I took it home, bored out the center of the rubber plug with a drill press, and fitted it around the metal pipe coming off of the valve cover.

i just loled at work thinking of the kid in you avatar saying that.

mine is "ceramic paint made for high heat exhaust" and i bet your can wasn't covered in flames like mine. aparently this paint is supposed to cool down the entire engine bay. i've noticed a significant gain probly about 50whp.

Well jokes on you, becuase next week, I'm putting a Honda badge on my heat shield. Lets see who has 50whp then...

So that filter is actually purposeful? I installed the FS cool flo intake and I just removed the tube and attached the smaller filter to the curved plastic elbo coming from the valve cover. Then I had the Focus in a dealership getting a wheel bearing replaced and when I got the car back the filter was gone. I just noticed yesterday but if its neccessary I'll replace it...
