First things first I do not have this intake yet. I am curious to see how hard ti is to install first. I know there is cutting involved. Is it required to take off the frint bumper in order to do the install? Do you have to plug one of the drain holes so water does not drip on the filter when it rains? Is there also a bypass valve in case of the filter sucking up water? Also how often do you clean the filter and does the bumper have to be removed in order to clean it? Thanks
