From the cazracing site: Nissan 300ZX TT Polished Stainless Steel Intake Pipe kit 300ZX TT SS HP kit $445.0 I bought these from Caz about two years ago, they've been on my car during that time. Asking price is $280 which includes the silicon cuffs and clamps.
I ordered all black but the boost couplers wouldn't fit. Fate came around and confirmed they would not fit, Caz tried some herself and found the black ones to be manufactured too small so she took the red ones off her track car and gave them to me.
