I know this has probably been asked before but...what is the opinions of a K&N intake for the 5.4? I guess more spacifically the 63 and the 77 series? I know the AF! is highly reccomended but I am just looking at other options?

 

I'm pretty sure the 63 gives the 5.4 more hp.

 

Any idea if either one has the droan that the Airaid has along with the evo?

 

63 has more HP than the 77, but i have the -77 and it adds some stlye under the hood and is cool when you open it up. takes away that black look and adds chrome.
