now i have thought of the filter, but was not sure of what 2 use, cuz i have two methods. 1st idea is have the filter inside the VX and being abale to change it from inside and stuff. 2nd idea, whitch i like better is having to use an old stock airbox that will fit the VX and is small but big enough to modifiying it and if for some reason water still goes in, it will collect under the box and when i check under the hood and if any water has added up in there, just clean it out. plus the 2nd idea will give me more room inside the VX and make it easier aswell.
