So finally it's done ! The sound is just GREAT !!!
I took some time to install it, but all by all it was not so difficult !
You have to REMOVE all the previous air intake parts, the first snorkle you will have to cut it, if you dont want to remove your front spoiler.
Then, you take the last 90° corner, just before the plenum, from this one you remove the little airbox attached to it and close the hole of this 90° part.
Then on this part you install the AFM in the right direction (follow the arrow), instaed of the big hard plastic spagethi thing.
On the entrance of the AFM you put the 90° angle that normally goes to the downside, connected to the AFM on original place (AFM is attached to the original airbox).
So on this 90° angle directed downwards, you attach the BMC-CDA (85-150), also again in the right direction. You can attach the CDA with a hole&screw used before to hold the airboxframe (big metal piece).
On the bottom of the CDA, you have to place the tube, when you start from the CDA, make a DIRECT 90° turn with this tube, or the tube will get so low under the car, that it will touch the road every time ! You have to install the tube in the front of the right air entrance of your spoiler, if it's sealed, you can or remove it, or make holes in it.
YOU HAVE TO ATTACH THIS TUBE TO THE CAR WITH (wth is the english name for this thin plastic zippers; tie-raps ?) sorry my english, i'm belgian :-) TIERAPS, or you will lose the tube ! I know it because it happened to me :-D
