Im getting ready to install a arlen ness airfilter/intake on to my 08 kingpin this week. I haven't torn the bike down yet but I know I will be taking of the seat and tank. Will I have to fully commit and completely take out the stock airbox or does it just drop in? Wiil I have to relocate any sensors etc?? I'm thinking the whole thing will have to be gutted. Let me know what I'm in for.
