Air Induction Pipes

[Bigears]

I have a 1992 FD with a HKS induction kit but only have the flexible pipes, and would like to replace with hard pipes.

Have seen these on e-bay   any ideas if they would fit.http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=36680&item=7923852488&rd=1

Hope the link works not really sure how to add a link.
