Think you'd go way cheaper and be better off with post MAF tubes, new filters and test pipes. Pretty sure the post MAF tubes and new filters were shown to give better low to mid end power compared to the stillen intake which gave gains in the high RPM's.

You can get ........ ones for 200 some odd bucks or find some good used HFC's or test pipes here on the sale forum, so that'd be less than 500 bucks total coupled with tubes and filters from Z1.
