Air box has been bone dry since I put in the S&E Particle Separator, I still check it to make sure everything is doing its job with no leaks ( you know how I ride LOL). I left the the Uni in place of the stock location and added the separator as the primary feeding the Uni. I spoke too soon on making it out of Busco unscathed. I found a torn front axle boot this morning ugh. Will be digging in looking for damage this week before replacing boot. 😎 Still lovin it though
