Better is relative
and it may need exactly the same ducting into the original airbox, but what it can do differently is the box mechanism and we can do some CFD on the airbox and ducting to ensure it's smooth.
I've been wanting to do a complex ducting project for a while and this seems like it might be it. Would combine it with printing in carbon fiber reinforced high temperature nylon which is good to 200C and with very high tensile strength which should survive any kind of vibration thrown at it.
