The instructions supplied needed the visual renderings to be larger..also the schematic of the parts very poor!

The kit here works well and I am happy that I bought and installed it. Nice filter and induction tube and hoses/clamps. The intake tube that connects from the throttle body to the airbox is somewhat tricky to get in, you really have to position it and snake it in correctly; I loosened some other clamps on the intake manifold side and rotated the throttle body piece upward. I ended up temporarily loosening the throttle body to get the tube into position then repositioned the parts. Runs smoothly!

Rather straightforward installation, one does notice a change to performance in the higher rev band. Definitely a change to engine intake noise on cold idle. Sounds like a vacuum, once engine warms it goes back to normal Porsche sound. At speed and higher rev though one can hear the intake once again when the engine opens the throttle. Don't really like the appearance of the alteration to a engineering design. Wish it was alittle less obvious.
