So it fits my 09 ralliart only mod you HAVE TO do is put 3" pipe connecters between the ic and the uper and lower piping. Now what you should do for this mod is get the evo ic upper and lower piping kit for the maximum airflow and cooling out of this ic. I domt know how much hp my whip gained but i can tell you this the ic for the evo is 2 times the size of the ralliarts also its going to give you pretty much the same cooling as a comparable 700$ ic(i got this used for 130 on ebay a few dings but nothing detremental to the efficiency of the unit, a quick paint in red and it looks brand new) that you would find at say lancershop.com do yourself and your wallet a favor and save almost 600 and get a used evo ic its a great way to add more cooling for way less than buying new.
Hope this helps
Thanks
Eric
