Minamoto Gen Super Jet Chamber set for ND Roadster. The manufacturer is no longer in business, so it's rare as you can't buy it new. If you're looking for one, please consider it. I had it installed on my ND Roadster before, and the intake sound was really great! (My personal opinion) There are small scratches on the exterior, but I don't think they affect the function. Accessories include stickers, gaskets (unknown if usable), and instructions. If you're an ND Roadster owner looking for one, please consider purchasing it. Thank you.
