You can do the same thing for about $200 less from Duffguards. Their splitter installs in your factory underscoop plate. Positive effects from splitters have not really been verified (that I have found), but the STi cars run them so that gives them some credence.
I think a splitter would definitely help direct air to the front of the ic as well as the rear. On mine I can't help but notice all the bugs etc are concentrated at the rear of the ic. I don't think one has to spend $250 to accomplish this however.
I think the original STI splitter to use with the STI Scoop and STI IC,,is 70USD at vivid racing.
STI units are expensive parts and 249USD for the zerosports splitter is a robbery.Zerosports are robbing people..
I dont think its worth to pay that amount for that piece.
Do you know how much is the STI water spray switch??49USD...
Thats a rob too..
