I have a barely used K&N 63 Series Intake that I took off of my 2007 4.7L Dakota. It is part number 63-1547 and is listed on the K&N site as fitting '07-'10 4.7L Dakotas. It's in great condition and will come in the original box and include all hardware and instructions. It's less than a year old. $200 shipped which is $100 less than the the $300 that other places are selling the new ones for.

 

Nice pic
