You can see from this where the clio has 2 inputs to the airbox, one from outside behind the lh side of the bumper, one from behind the headlamp. For me they just left the other pipe in place so i could put it back to standard. You can see where they have used the engine bay mounting.
This is a graph of before and after Dyno run. You can see the car gained 8.5bhp from standard, ie no mods. Tho the torque figure is well out. That figure makes the car have 433NM when the car is 200NM as standard. Therefore i cant be led to believe that the dyno run is correct or not..
