Spent today doing the airbox mod to my dci 175 also ran a cold air feed to the front grill,i was expecting the airbox and intake to be the same as the 225/R26 but once i had removed the battery tray etc you could see its clearly different!!any way got there in the end after a lot of swearing :D you can now hear a deffinate change in engine note at around 3000 rpm i think it sounds good even better when i get my custom back box done.

I took a couple of pictures of the pipe i removed if anyone can shed and light on it runs an intake from the front upper grille but i can't work out what the small pipe is for...

You should of left that pipe in place really, it looks like an intake / airfeed.

Dont think its that the small pipe is blocked off one end its a very odd setup maybe its designed to keep the induction noise down?..does sound good now on boost just a pain in the back side to do!

Looks strange, but could be for acoustic purposes... Or maybe fits another Renault model?!

Thought it could be a silencer the small pipe is only attached one end and is blocked off the other... You can deffo hear a change when around 3000 rpm now,under the battery tray etc was exactly the same as the 225/R26 apart from this pipe that runs to the upper grille.looks like renault had try to make the dci sound more refined by using this?

Quick update,i wasn't happy with my current setup cold airfeed from the front grille so i spent today chopping a bigger hole in the airbox and re-using the old airfeed that came fitted to the car sounds great now and im getting a really cool chatter when on boost changing gear:D

As above mate loads of info if you search airbox mod... One bonus with the dci is it comes already fitted with a caf from the grille....
