I have replaced my IAC once. The IAC that I cleaned successfully was the replacement IAC and not the stock one. At least for the 2000 V-6s there was only one part number from the dealer where I bought mine from. I even asked him if the SVT was any different and he replied no. The 95's might be different but I am pretty sure there is only one part number for the 2000 2.5 IAC, SVT or non-SVT. The other years I am not sure about.
