i have one on my series 2 and i had the same prob.the replacement rad bracket you get fitted ok on mine but yeah the boost hose and rad pipe was really close,i had to ease the rad over only by a bit then clamp the boost hose on,it does make it easier if you are using samco hoses as i found the standard one abit thicker.Other than the hose problem i found the intercooler works spot on and still have no probs with it,just bit of a poor design i think.
