On the 97 Mustang, the UDP is probably the easiest install you'll ever do. You take off the belt, unbolt 4 bolts to drop the old pulley, bolt the new pulley in its place, and put on the new shorter belt. I did it in about 20 minutes on my 98 Mustang.
You're starting out the same way I did. My first mod was the CAI, then the UDP shortly afterwards. The 2 combined will let you notice your car "pep" through the RPM's a lot faster than they are now.
If you need any help, feel free to ask. We'll be happy to help ya :mrgreen:. By the way... good choice on the 97... because 94-98 Mustangs are the best
