I would just buy it for a 2009 and put it on my 2008. As far as I know there were no changes for that.According to the PC website, the PCV only "Works with 2009 or newer Motorcycles, ATVs and Other Quads". I double checked by selecting the 2008 TRX700XX in the dropdown menu, and the only option to buy is the PCIII. Once I changed the year to 2009, the PCV was available as was the Autotune.
<------2008...So I guess all us 2008 owners are SOL on this. :lame:
