I have no car to install it in for another week or so so can't comment on its use, but it is built to what appears to be a very high standard. Both scoop and airbox "bell" are carbon fibre and polished on the outside, bare CF on the inside. The supporting heat shields are high quality too with rubberised ends and foamed inside panels. The tube appears to be of OE quality construction too.
It certainly looks and feels expensive. I have not RTFMd yet to find out how to clean the red filter inside. I imagine dust and crap will collect on it as time goes on, so something to add to the weekly checklist when washing the car.
Mine is number 298. Surprised so few have sold!
