Answer to this question is really simple. There's really no abundance of space in Clio bay, so make them as long as possible.

Make them as long as you can physically fit under the bonnet with enough space for decent filtration without smothering the end of the trumpets;

With bike parts, your biggest concern will be more finding some with a large enough throttle plate. Most bikes use 38mm or less. Overall length will just effect torque by a handful of lb/ft
As above. IMHO, somewhere around 33cm is doable on F7 series engine in Clio, but with special MAXI style plenum.

This is from the head, not valve.
