I don't know how much they run for, but the 97-96 intake is good for something like 15ft-lbs of torque. One of the reasons for this is that it is made of "high strength composite material." Read: plastic. It has been known to crack. On the old forum there was like 8 billion people on there who had one crack. Read that. My 97 is just over 70k miles........orginal intake. I don't know how difficult it would be, I think most people just go for the SVO or Bullitt intake.
