    Well, what was it? I remember it being a smidge bigger than a round number, like 3.25 inches or something. That's why I went up in size and squeezed it down. But you should post, you know for when someone has to search in the future :)

    So i finaly got round to fitting the new air ducts. So i am posting it on here solely for the archives in case some one needs to know, as J Salmon suggested.
    So the dimension of the silicon air tube needed is 80mm's, although the 83mm will also fit easily. The cost of this duct hose is £19 per meter, so thats a saving of approx £400 that you would pay Ferrari for the identical stuff.
    Hope this helps some one.

    If you look at the front grill. Its at each end of it, behind it. There is a large opening at each side.

    Where did you buy the hose from? I see the link to the eBay seller, but there's is 1 meter length - do they sell longer ducts?

    Thanks

    I assume come in all lengths mate. I linked to that particular link because a meter was all that was needed for this job. But like i said i assume they do all lengths, its motor sport ducting after all.

    Reviving this thread for anyone searching 10 years later. Funny enough, I now have J's car and the ducting on each side has shredded at the rotor clamp point so I'm ordering some new stuff. Like everyone here, I checked Ricambi but each hose is $200 (so $400 total since both of mine are blown). BS Ferrari tax, so I'm ordering some silicone ducting from Pegasus. I measured and the vents are just above 3". Around 3.25" ducting would be perfect, but since that's pretty much nonexistent, I'm going with 3.5". It's a bit smaller than what J used, which I think might be better as the shredding occurred right at the clamp points and might have been exacerbated by how much he had to clamp down on the 4" hose. Although, his replacement ducting is almost 10 years old, so it very well could be that it was destined to die by now anyway, but I figure anything to reduce the stress on the tubing will help.

    Getting my ducting here:
    https://www.pegasusautoracing.com/productselection.asp?Product=3621

    3.5" and 3 feet should be more than enough since the actual gap is only about 7 inches... so with flexing during turning 18 inches on each side should be just fine, it looks like that's about what J had on the car previously. It comes out to be about $55 with shipping and tax... much better than $400.

    Hope this helps anyone coming along after me!
