Those are actually pretty cool, induction resonance optimised intakes. If you can tune the resonant frequency of the intake to peak as you hit max power you can increase the volumetric efficiency. These are good on a race car as they generally tune the intake runner for operation around in the smaller rev range that it will be working in, for a road car it is less than ideal as outside of this range the resonance will have negative effects on efficiency. If they have some way on this to vary the runner length that would be really really cool, I don't know, but that would definitely need a pretty fancy ecu.
