So it looks like the tiny tube inside the SRI portion is riveted in behind the Injen plate, which is just held on by 3M tape. So it is possible to peel this off and burn out the rivets, pop out the mini-tube, reapply the 3M with the logo and you're back to a normal intake tube.

Of course, you are still dealing with a CAI that will probably get wet, and heck any cold air (who else is out there? Descendant? AEM? any other CAI?) that drops into the fender seems like it will do the same thing.

 

Just a FYI guys, that Air Fusion tube inside the tube actually does the total opposit of what you just stated. That tube actually slows down air at low engine speeds and accelerates the air at high engine speed. It also keeps your short and long term fuel trims low so it wont trigger a CEL light like some other intake companies. I work very closely with Injen Technology and I've seen it in action and I've seen the affects with and without that tube in there.

 

I wouldn't remove that tube. It serves a purpose and the car will run even leaner if removed. The Injen intake does run slight lean in the beginning of the powerband but look how much power you are making there, about 80hp at 3100rpm then it fattens up from there on. Any tuners can chime in and give your input but I've tuned lots of cars and running a WOT 14:7.1 aif fuel at 3100 rpm making ony 80hp would be ok and ideal on an naturally aspirated engine and then fattening it up as RPM climb as with the Injen intake.

 

Here is a really good example of how lean you can run air fuel at low RPM and low horsepower. This is a brand new bone stock 2012 Ford Focus 2.0L. Red is bone stock and blue is with Injen intake. Just A FYI guys.
