i know on the ss/sc ther is complete plastic on the bottom so we dont worry bout hydroloc but idk on the other balts so idk. Be careful around puddles

 

yeah puddles were a good issue...but im not running on that set-up anymore...one day it rain hard as hell over here, when i got home and checked it, the filter was soaking and dripping water...so i changed over to a short ram intake...
