hey, i went by my local performance store today, i was asking about Ram Air intake for our cars. Shocking to hear they told me that it is available and they would charge me $280 for it. Thats kinda pricey but it looks real nice. And another thing if you look at the 350z Race Division CAI http://store3.yimg.com/I/ntnsracing_1748_6825511 you'll see that the first half of the CAI acts lik a ram air pipe, then you can jus put any air filter to the other end of the pipe... and i don't think it will cost as much prolly $250... just a opinion
