I have the Trinity and love it. If you go as far as completely removing the air box, let me tell ya a little story. 2 weeks ago I was in the Ridgecrest Gran Prix, some had their box all there, some had just holes punched into it, some had it completely gone. Now right smack dab in front of the grand stand was a 70 long, 2 feet deep water/mud hole one had to traverse. The funny thing was, the peeps with no box sucked water into the motor right in deepest part of the pit, people like me who had several holes in their box made it about 7/8th of the way through before flooding the motor, and the peeps with full air box, well they ran right on through the pit. This is how I ended up with a 2nd place instead of a 1st place, I watched a freakin Honda blow right by me as I was cranking the LTR back up. Here are some pix of the mud.
If you anticipate any kind of water in your future, I would not remove your airbox, and upgrade your air filter over the stocker. Oh Yeah, my K&N did keep the intake almost spotless inside the runner, although there was some water seepage.
