Re: KN air filter and induction kit
You need to get a bolt on Tophat adaptor and bolt it to the electrical box. The adaptor has a square end to bolt onto the induction box and a circular hole to accomadate the new filter. i have a 93 GLXI colt and it is a bit of work and messing about, i had alot of trouble with room because of the pipe that the electrical box fits to was too long so i cut it in half and just fits in there nicley. i got my adaptor from Motor World and had to order it, so id go there or Halfords and just ask.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

the black air induction to bring from air filter to throttle body somewhere on the middle of it will be the intake air temperature sensor it is a two wire connector it will be the the only electrical plug located in the air induction tube if it is not found there it will be located on the side of the air filter housing
no with air induction you should be fine. The computer will adjust fuel air mixture. When you add a different exhaust system is when people run into trouble. That changes back pressure and can cause the engine to run outside of computers control..
No, you don't need any firmware changes. Something else went awry with the installation, or it is a coincidence. The system will make a slight adjustment over the next few driving cycles, but you should not notice any performance difference as it adjusts.
Look for a leak between the mass airflow sensor and the throttle body.
The only thing you gain with a K&N induction kit is noise. If you like the sound, great, it is your car, but even if you keep the filter oiled (which few people do) you let more dirt into your engine. Be sure to keep your old filter box because the car will be harder to sell with that filter on it.
A 2000 is an e46.
Actually, the newer ('05+) Duratec motors have a sealed airbox. There is a meter on the side of it (positioned just behind the driver side headlight.) To qualify as a Partial Zero Emission vehicle all emissions parts are required to last for 100k miles. 100k miles is when Ford recommends replacing it. Yes... you replace the ENTIRE airbox. Often times it's more cost effective to replace the unit with a traditional cold air induction kit (~$150) with a more traditional air filter.
is this one of those cyclone cartridges you put in the intake hosing? if so then dont waste your money, the power gain off of one of these is not noticable and the fuel economy wont change enough to make a difference, the engine is gonna draw air in at whatever rate it will, the only way to change that is with forced air induction (ie turbo, supercharger, blower). these things only help to mix the fuel with the air a little better so you get a more even burn and less wet spray fuel making it into the cylinder. forced air induction works by changing the volumetric efficiency of your engine, say you have a 4L engine, running naturally aspirated in 1 cycle that 4L engine draws an average of 85% of that 4L, if you put on a turbo or blower or supercharger you make that engine draw in more than its 4L capacity so your 4L engine would be running at say 120% of that 4L, trying to compress that much more fuel/air mix is where you get all the extra power from. ill save the explanation of an intercooler for another day....
have you check air filter and its intake if this is clogged or damp it will restrict air flow resulting in black smoke due to more fuel than air induction make sure you remove filter element and check underneath as this is the induction side of filter the top may indicate it is ok cas it looks clean fit a new filter useless to try cleaning because if dirty ? the microscopic holes in element will be clogged even a damp element will restrict air flow recheck all induction air hoses are secure and not split/cracking?
If you had one put on did they reinstall the airflow meter. This would cause a lot of the problems your having. Also there sould be a breather tube coming from the valve covers to it and if it plugged it would cause problems.
