Had a Viper with a sh*t cold feed, (see pic)
looked ok, but decided to put it too standard partly for insurance reasons. Put an ITG in there and much much prefere it. The standard airbox is well designed by Renault, the induction kits seem to be a bit of con tbh, although obviously I can't speak for the maxogen etc but its costs an arm and a leg so I would never bother.
The chap who mentioned matched inlets & RSremap is dead on, its a no brainer in my opinion if you want an actual performance gain!
