Recently got an AEM Brute Force Air Intake System with DryFLOW Filter (no oil required) and installed it on our Aug.'04 build 2005 Midnight Blue 300C (test bed for eventual install on the '06 Heritage Edition).
Here's an illustrated documentary about the installation. Let me know if you have any questions, and I or someone from AEM (whomever is their forum monitor/moderator) will try to answer them.
This is what arrived and all pieces were well packaged (foam peanuts) in the box.

The Project:
Does it take automotive skill/experience? NO!
Should you read the instructions? YES! (I'm a man... I can change!)
I had not really “worked” on a car for many years, so I was concerned about how easy, or challenging this install might be. I was pleased to find that it required simple, everyday tools (regular screw driver, 10mm and 8mm sockets and wrench), was relatively easy and took me just over an hour from start to finish.
This is the stock intake system of my 2005 Chrysler 300C. The first step is to remove the engine cover by pulling straight up on the sides to disengage the 4 positioning posts.
Then disconnect the Intake Air Temperature (IAT) sensor at the elbow of the intake pipe. This involves two operations. First pull back on the red tab. This unlocks the connector's security clip, but does not release the security prong.

Then press the back of the underlying security tab to open the connector’s hold-down prong.
The connector, then, will slide apart easily. Without this, you can NOT get the connector apart!
Loosen the stock hose clamps at the throttle body, and the filter box.
Then remove the intake tube. Loosen and remove the filter box mounting bolt (10mm) at the front right rail of the engine bay.
Keep the bolt because it will be reused. Then remove the valve cover breather hose from the rear of the filter box. You may need to twist gently to pull off the breather hose.
The stock air box then lifts up and out of the way.
