Hello, I just bought a 2017 1.0 ecoboost.  remapped with a superchips map today. Curious where the recirculating valve dumps to exactly? Is it the intake manifold or somewhere in the intake pipe before it?? IV seen the st200's airbox but I like the extra capacity of the 1.0 airbox. I might cut maybe a 2" hole and design a duct to angle over towards the  front bumper and 3d print it. Anybody do this before , any pics ?

My ghetto airbox modification. 

That's looks pretty good , I found a secondhand mountune airbox cheap enough so going with that. Did your mod increase engine noise by much ??

No noticeable increase to engine noise. Much more change from an aftermarket secondary intake hose. It did decrease stationary intake temps though. 

I've started acquiring parts to do this. What type of hose did you use and where did you place the inlet end?

I was planning on aiming towards the lower grille.

Hose was an ebay aluminium expandable hose. Inlet towards the front down near the fog light. You might find a 2nd hand Mountune or ST200 hose on ebay
