I removed mine from my GSR and it was really not all that hard. Make sure you drain the refrigerant first and then start removing the lines, compressor, etc. You will need to remove your battery and intake to do this. If you choose to remove your evaporator from inside the car you need to buy two parts from Acura (I have the part numbers at home) for about $50.00. Removing the evaporator is a real PITA and I had to take my airbag out because I did not have a deep enough socket to reach one of the bolts on top.
