i am new to forum and new with my 04 pred, i have put on full yosh exhaust , k n filter and dynojet jet kit, it f"n screams!!!! i thought about the cfm air box and the others , but it will sacrifice the air intake level, i ride trails only and sometimes come across a deep water crossing, and i dont want to suck the motor full of water!!!!! does the cfm and other airboxes lower the air intake level and does it give the bike that match more power for 150 bucks!!!!! come on guys does the pred need more power??????????? peace!!!!
