n designing out the stock air box, we always try to design in the largest air box that we can. When replacing the stock intake tube as we do in our Stage 2 systems, you have more flexibility since you can change the tube configuration. However adapting to the stock intake tube forces some limitation on the design. Even with adapting to the constraints of the stock intake tube, we are careful to use that stock mounting points. There is no need to cut or drill anything when you install our kits.
