O.K. I admit it, I'm the cautious type when it comes to even simple stuff like this. I bought a Uni-Filter, cut out the bottom out of it, and then cut a corresponding hole in the bottom of the airbox, leaving the little tabs that hold the filter in place. I see a space and then a apparently a second bottom to the airbox. Do I need to drill thru that as well? It seems like more air will get thru with what I have done, but I wanted to see what others have done. After I get thru with this stage I'm going to tackle rejetting which should generate lots of questions from me. But first things first, what say you all! Thanks in advance ..
