*cough* I've only gotten that filter soaked once and that was while it was parked during that huge storm. My dumbazz decided it was a good idea to park the car FACING the rain so the filter got soaked... it only ran bad above 4500 RPM though until I got the new filter in the next morning.
BTW, I've got about 3" of tube before the throttle body so I think it adds a little velocity there... just enough to even out the gains, I think.
