Slow boat from China?

Well I just received an email from Advance Auto Parts that my aFe Power Magnum Air filter has been shipped. The lasted I heard from them they were cancelling my order,WTF? Well I guess I will compare this filter against the K&N I purchased. Extra parts sometimes are a plus.

Question I have is has anyone noticed any difference since installing any of these performance filters? I am looking for any mpg change or throttle response. Also when I had the K&N in my crown vics I noticed louder engine noise is this true in these?

I am getting about .5 mpg increase over the past 1000 miles since I added aFe filter. The K&N filter was about the same but I did notice that the oil from the K&N was creeping up the sides of the air box.
Yes it is slightly louder with the K&N or aFe filters.

finally rec'd and installed the aFe MAGNUM FLOW PRO DRY S AIR FILTER SKU: 31-10215 earlier this week. I haven't driven much but this weekend I should get a few miles on it.

Update - there's a noticeable difference in smooth throttle application, esp at low speeds. It seems like the car had to adjust to the increased air flow b/c initially it was laggy, but after a few miles this went away. I like it. I need to do a new dragy to see if there is any performance improvement; currently 0-60 at 4.36 BEFORE aFe filter is my best time thus far.

Definitely felt the lower throttle being a lot smoother as well. Curious to see any diff in MPG efficiency though.

I actually felt the opposite,

Complete loss of low end torque and rough shifting off the line with the aftermarket Dryflow filter. Switched back to paper filter and the car is running so much smoother and better throttle response in low rpm range.

I went with the oiled Afe filter. Maybe the oiled particulate made the difference???? I just know with the my oiled filter it’s smoother on acceleration from stops.

I had a similar experience initially with my Dryflow. I actually switched back to OEM paper after a couple days. I then read somewhere that with newer Ford vehicles, after changing the filter, just start the engine, don't rev or touch the throttle. Don't do anything. Just let the car breathe for at least 5 minutes. Apparently there is a calibration process that will try to optimize airflow, and some other factors, based on current conditions. But you need to give the systems a few minutes to do all the math.

I did this after reinstalling the Dryflow, and have not looked back. Might want to give that a try. Maybe it's a myth. But it don't cost nothin'. And it seems to have worked in my case.

Or you could burn incense and chant. Guys, I'm seeing posts talking about the ECU somehow adapting to airflow at idle, requiring 5 minutes to "do the math" and magically "calibrating" some sort of airflow optimization etc. It's not happening. For the ECU to do that sort of thing, there would have to be some type of sensor right? So where is the sensor for pressure differentials between the air filter and the speed density measurement system? There isn't any. I'm not trying to flame anyone, but posting about some kind of huge difference in idle quality, transmission shifting, and throttle smoothness, isn't supported by anything other than your subjective butt dynos.

now thats more like it, 19.2 mpg. trying to get to 20 mpg. only switch to sport mode and open it up on highway once every 1 or 2 weeks just to keep the twin turbos active.
