you'll need a sharp blade like a stanley knife to cut down the 90 degree silicon hose slightly. If you don't the cda will get in the way of the bonnet shutting or at least thats what I found when doing mine.
you can see how I put everything together in this pic:

The Silicon Hose Kam Racing normally supply are 5mm to wide in terms of diameter and a lot larger than they should be hence having to cut them. Your best bet is to use the correct BMC 90 degree bend (SAC - 09070).
That fits perfectly without having to cut things down.

yeah i had a look at the weekend and realised the silicone hose supplied was way too high and even with the reducers it didnt seem to fit round the throttle body properly?
where can i get that proper bmc hose from if u know?

Yeah it is far too big. You can get the proper BMC 90degree bend pipes from Venom Motorsport and Demon Tweeks.
Any company that supply the BMC kits should have them available so it might be worth trying a few companies.
Make sure you give them the correct part number though SAC - 09070. I think I paid £12 for mine which is a little steep but the Samco versions are normally £20+.
The BMC pipe fits perfectly on the throttle body and there are no issue's with height clearance on the bonnet.
I recommend cleaning the throttle body before you fit the pipe with carb cleaner.
To answer your other question regarding the engine cover you shouldnt have any problems fitting it.
I will upload a pic of mine when I get time, because I also have the cover still fitted with the BMC, the
only thing you may need to do is modify the Mechano bracket that comes with the kit.
I will try and get a pic for you later on.

thats brilliant thanks a lot mate. think i will order the proper pipe as i dont really fancy chopping away
that brackets massive too lol did guess it would need cutting. and thanks for the advice on cleaning the throttle body. think i saw a DIY guide on how to go about it on here so ill use that.
shame it wont get done til a couple weeks time, would have been cool to have it done for ed38 and trax...im more than happy to just have it tho after being on the hunt for months!!

No problem at all Jack,
You will love the sound of the BMC when you get it fitted, its certainly the best sounding induction kit on the market.
The standard air feed that comes with the BMC is not the best either, it does the job but doesnt look brillaint as far as engine styling is concerned. At the moment I am using the BMC air pipe connected to the OEM Volkswagen air feed which is really poor but that's because I need to buy a better cold air feed.
Check out Tim_Gti's build thread, his engine bay is spot on.
