ok, i installed it the best i knew how to. the instruction where soaking wet and i couldnt really read them cause the package was left out in the rain, but anyways i took out the old air box and set it up all right according to the picture but the other side of the tube(the one near the fender where the opening is facing the intake) is just sticking out there with nothing around it and i didnt notice too much of a difference of performance just a loud noise when accelerating. am i supposed to attach that tube to something or just leave it there? thanks. also my check engine light didnt come on after install so does that mean i did it right and got luckey or is something wrong.
