The bell has to help...You can buy them with a filter for $25 to $100 (25 is used but thats ok). This setup is like version 5 beta...the next setup will be better, the whole cold air box is the bell w/ a flat filter on top...very similar to stock, but not. It will still be "ram air".
The current version would need a tidal wave or a deep (4-5')puddle (that is feet not inches)to get enough water in but I would still like to improve upon it for safety.
The other bad thing is its tendency to make you go over the posted limits because it is pulling past the current limiter
