In my opinion... go with the 360... its cheaper and looks a hell of a lot better. I have nothing but good things to say about them. Plus now you get to pick what color you want your intake - they didn't have that when I ordered mine a year ago.
i just got a K&N and i havent had anyproblems with it. it should be a relatively simple install (wen you folow the dirsctions) and it seems to work. it sounds awsome but i have yet to notice a boost in fuel economy.. havent had it in long enough. i assume that the louder noise means more power. it definetley sounds faster.
