fun. like a treasure hunt. not much info to go on. a red herring thrown in there to boot. the first image you provided had 'sharkwerks' stamped on it, so easy to find. that was an image of the sharkwerks 997 turbo plenum, so wouldn't work on our cars. at first you would think that the carbon plenum in the second image was related, as it was a carbon plenum with 'werks' on it. not so. no such product. so, i check the file name of the image you posted and it had 'tpc' in it. aha, i say, tpc has a carbon subsiduary. not so, as nothing on the tpc website. then i google 'tpc carbon plenum' and voila, werks is a subsiduary of champion motorshorts.
should fit the boxster (with larger throttle body). nice unit.
