04 F-150 Air intake

I have a 04 F-150 with the 5.4L engine and an automatic tranny. I just installed a Borla exhaust which made a nice addition. The next obvious step is to install a new air intake. Problem being, there is no information out about any for the new truck. Could some of you please tell me about your experiences with the different brands such as K&N, Airforce One, Airaid, etc.... in other years of the F-150. Thank you for your help.

BTT as I'm interested in hearing any opinions as well.
