josephd The car never came with an owners manual. I downloaded the one off the internet but saw nothing about how to test the filter. I will look into it.
Update: I found it and it is plain as day. I was wondering what that plastic knob was on the side of the air box. :-P. I have no worries, it is on the 1st mark inside the green. I started the car and hit the reset button, and that is where the indicator lies.

whynotthinkwhynot You don't have an owner's manual? The directions about how to test it are in there. It's easy, IIRC, you simply start the engine, allow it to idle, then press and hold down the button and check the reading on the gauge there under the hood. The button/gauge is right behind the driver's side headlight. Go check your owner's manual, it's under routine maintenance. I have seen where those filters were damaged and the filter filled up with leaves or water, but you'd know it because it wouldn't run right.

Yes, it is possible that there will be codes generated. I would guess codes like O2 sensor reading lean, or MAF not reading correctly- as a guess. If you swap over to a CAI or simply put a 3.5" cone filter on the end of the MAF tube, then you will want to purchase some MAF cleaner and a Torx screwdriver so you can remove the MAF and clean it. The oil from those filters will contaminate the MAF and cause bad fuel economy. The MAF should be cleaned weekly for a month. After that, simply clean it with each oil change.
My car is running fine so far. I have close to 82K and tend to be OCD on non serviceable parts. I did an internet search and cannot find where or how to test it. What I did find, Ford says 150K is the usual expectancy of the filter.
I was also told not to worry about either or. If you're not in very dusty conditions, the filter rarely needs replacing. And keeping up on the oil changes will keep the PCV from clogging.
At 70K I changed the plugs, fuel filter and anti-freeze. The fuel filter I am over the top. I change it every 3rd or 4th oil change. I am on the 200K plus quest, hopefully she will make it. :) Thanks, for your input

You do not have an air filter to change. 05-07 were equipped with a lifetime air filter. Your owner's manual will tell you how to test it. Most of us replace that with an aftermarket oil/cotton filter and CAI instead of purchasing a new $200 lifetime filter when the OEM doesn't flow correctly.

Cleaning the MAF is not a bad idea, and costs about $7 for a can of spray MAF cleaner. Around 100k miles is when I replaced my coil boots. You might have noticed that you don't have plug wires and a distributor or even a coil pack like older vehicles. You have coil on plug ignition. Those are the coils that sit on top of the valve cover. We have had problems with the clips connecting the coil power wires- so check those to be sure these are all connected and clipped in place. To replace the boots, remove the coil and boot from the plug. Twist the boot to break it loose, then fold the open end of the boot back towards the top of the coil, and it will pop loose. You can also just pull or push it off the coil. A new boot will cost $5-8 each, and will come with a new spring and solid conductor.

Fuel filters should be changed every 25-30k miles. There is really not much you have to do to this car as far as a "tune-up". Plugs every 75k or so if you use platinum or iridium. NO, they do not last 100k. Coil boots are changed right around the same time, you might get 2 plug changes. The MAF should be cleaned every 25-30k when you change the fuel filter. You can check the PCV at this time- but it's very difficult. As far as fluids go, just keep an eye on them, and change as needed. If you have an AT, then you might consider changing fluid and filter around 100k, or 60k or so. From what I understand, the new fluids last much longer than the old fluids did.
This may be a silly question. Aside of the car running poorly. Does a check engine light come on indicating, time for a change? The OEM filter not flowing correctly, leaves me to wonder if it would cause other problems within the engine.
Any idea what the life expectancy is for the OEM filter? My 07 has one of those maintenance free filters. IMHO that and the PCV being behind the manifold, is not one of Fords better ideas. Thanks

whynotthinkwhynot ^^^ FYI: 05-07 simply have a metal screen there, there is not a cabin air filter folder like the one shown in the picture above. That is what the part looks like that you'd have to find on a 00-04 Focus in a junkyard if you want to have a cabin air filter. Then you have to remove the metal screen and it's plastic frame, then put the cabin air filter holder in it's place.

They never came with 'em; but you have to spot to install it. You'll need to pull your wiper arms (index the resting position so re-installing them isn't guesswork), and cowl to get access to the cabin air intake (under the passenger side cowl)...







I used Ultra-Black RTV sealant to reattach the cowl and assure no leaking into the passenger's footwell via that opening under the cowl!

Dukttape Also grab yourself a bleeder kit and do your brake/clutch fluid. I'll be rolling on 30k here in the next month and I'm going to be doing oil, tranny fluid, and I'm buying a motive power bleeder from FSWerks and going to start doing the brake/clutch fluid every spring. I'm also putting in magnetic oil drain plug and this fall a bypass filter system in, which gives 2 oil accesses ports to run temp and pressure gauges , and I figure more filtering is a good thing for a DD.
