Eric- Well, I finally go an email back from the guy and he said....."Filters? You don't need no stinkin' filters!!!"
Like I said earlier, the only times I've seen his engine he simply has the alum tops (screens) on the stacks (with the holes). -Don't know what they're "official" name is called. He said that every time you go from the screens to filters you have to re-tune the engine and it's a PITA (which is why he doesn't change it).
And as for measuring clearance he said......."How do I measure the clearance? When the hood is closed, I can't get in there to measure! All I know is, the hood closes and doesn't rub when I'm driving. That's all I care about!"
-Sorry.........not much help.
