Why don't you try looking on the CEG classifieds and for that matter, post your needs on the classifieds too.
I would not be surprised if the intake parts were close to $300.00 if you bought them new, but I've never checked.
I do remember a used car Acura in our shop with an aftermarket intake on it that needed to be converted back to factory to pass smog a few months ago. The parts needed ran close to $500.00. It was enought to make the used car manager pause before authorizing the work. The car was otherwise in too good of condition to wholesale.
