my cousin saw my altima, and all i have is a wai. he rode in my car when it was stock, and he said that he could feel the difference. he wants to know if there is a cai or even a wai for his application. i tried to search yahoo and ebay, but didn't want to put too much effort into it. just wanted to see if there were any stanza owners out there, and where you get your after market parts from.
