Hi Paul Patt, sorry I'm getting back to you so late. Here's the forum thread I used for my replacement parts: www.focusfanatics.com/forum/duratec-performance-2003-2007/755762-%2430-performance-intake-using-factory-parts.html
Wow what in the world do you drive through? I watched a couple videos with these awful foam filters and decided to swap out the lifetime box for an aftermarket box with replaceable filter on my '05 a couple years ago. 150k+ miles and my foam filter stack was virtually immaculate. The first one was slightly grayed in the corner, but that's it.
I have the same car; I'm considering working on the air filter as well. I was thinking of replacing it but I'm worried about the quality of an aftermarket filter. Looking at how clean those bottom foam layers makes me wonder if it would be worth it to cut open the box and clean it instead. It's a stupid design but seems to filter well.
Okie. Sorry but with all that foam that engine couldn't breathe. I bet a cold air aftermarket which I'm going To do will run better but can't promise any better MPG..
I have a 2007 ford focus 2.0 duratec that I use as a daily for work...140 miles round trip M-F. First I removed the "lifetime" filter completely and replaced it with a K&N Sri Typhoon system, then replaced the 2nd catalytic converter with a Magnaflow Hi Flo converter/resonator delete, as well as a Magnaflow straight through exhaust muffler at the end,( all new piping from the new CC back.) The power, mpg, sound, everything is MUCH better, transformed the car essentially. The original lifetime filter and tubing are extremely restrictive. In the future ill replace the manifold and 1st catalytic converter(that are one unit) with a Magnaflow header/ Hi Flo cat unit oem spec.
K&N makes lifetime filters, but they still let you access the filter itself for periodic inspection/cleaning. This was by far the dumbest design Ford has done to date. I didn't even realize the intake tube was a plumber's nightmare. Jesus, these engines make 145 hp stock. Seems you could pick up 5-10 hp easily by ditching all of that bull shit in favor of a cold-air intake unit.

Because I did the same but ever since the pcm throws a code saying iat circuit high and maf. I unplugged the sensor and car works but plug and has drive issues and turns off
At around the 45 second mark, you'll see me tap an air filter adapter and an air filter. They are from a 2012 Ford Focus. Here's the forum thread: www.focusfanatics.com/forum/duratec-performance-2003-2007/755762-%2430-performance-intake-using-factory-parts.html
I cut down the tube with the mass air flow sensor in it and put a cone filter on but I am getting a check engine light for 1. mass or volume air flow circuit low 2. system too lean The car is also running poorly Any ideas?
Good video- I would like to know more about about your DIY assembly ? New filter in new box etc ? Part #s ? -Thanks

You can go with this basic setup and get the filter from Ford.
@@KalebMarshallDulcimerPlayer How much is it?
@@MattJasa It was 35 USD when I made the video. No idea what it would be today, but salvage yards would probably have the parts for real cheap.
@@KalebMarshallDulcimerPlayer Thanks Kaleb. One more question, can I buy it online? I didn't see just the filter at ford website.

There was no noticeable increase in power, but the car had 250k miles, so...

That breathing gave me anxiety lol
How did you get the filter housing open? I couldn't open it.
un_COG sorry for the late reply. I went with an alternative solution for my air filter, so I simply broke the box open. Smashed it with a pipe, IIRC.
We're in the shop trying to figure this out too. Lol and thenI read that comment. Head mechanic says it make sense lol.
It is supposed to be oily....that's how lifetime filters work.

That filter is fuggin brilliant
How did you open air filter box ?
Bashed it with a pipe.
Did you replace the air filter box a box that has a replaceable filter?
Yes, at the 0:50 mark you'll see me tap the new air filter. It's one of the 2 parts for a 2012 Focus which I bought.
Here's the forum thread which I used: www.focusfanatics.com/forum/duratec-performance-2003-2007/755762-%2430-performance-intake-using-factory-parts.html
Did you have to replace mass air flow sensor? Or stock 2007 sensor
I used the stock sensor.
Because I did the same but ever since the pcm throws a code saying iat circuit high and maf. I unplugged the sensor and car works but plug and has drive issues and turns off
@@anony3u5mnd54 Was the MAF installed wrong side facing forward?
How you install new filter?

Any ideas?
Nicole Nowak Dickinson Try turning the mass air flow sensor around. I believe it's unidirectional.
