I thought that I would post this up as it might be of interest to some of you.
As you may have seen in this thread, the intake hoses are prone to collapsing, discolouring and the foam disintegrating through age. Also, they are no longer available through Service Citroen.
By chance I might have found a small supply of these through my supplier and have managed to get my hands on one at the moment.
Here's a picture with new and old for comparison - obviously the new one is straight until fitted when you'll bend it and it'll take shape.


I do not know how many my supplier has got, and one party has first dibs on a couple of them at the moment.
If you're interested it'll have to be on a first come first served basis due to not currently knowing the total quantities available.
Price-wise, they are £30 per pipe plus £5 postage. If you would like more than one then just one postage fee.
If you're interested then post or PM.
Thanks!
