I'm getting ready to install my FRPP Bullitt style CAI plus a tune (TBD). Since I happen to have a 3D Carbon center fog grill, I am looking at the possibility of adding an internal under hood "scoop" to add airflow at speed. Attached is a photo with mark ups and sketch of this concept. (not my car, but a good photo) I would probably cut and score the plastic radiator top piece and bend down at a 45 and add side pieces to make the scoop. As you can see it would be in the area of where the stock fog light would normally be. And it would be right in line with the under hood air entrance to the FRPP filter bucket assembly.

A question is - would this modification help or hinder the air flow to the CAI? My obvious concern is at speed I don't want this "scoop" to cause turbulence such that the performance of the CAI degrades. Thanks in advance.

It wont hurt anything...but wont really help much any. not gonna see any HP gains..etc.

Yeah, won't do squat performance wise.

style only, though it will add some marginal drag

I wouldnt do it. Doesnt seem like you;d gain anything from it.

It won't add any airflow into the intake (as mentioned above) but it may allow a fraction better engine block air flow. These engines heat soak something fierce and although the airflow will help with that, it won't do enough that's even seat-of-the-pants noticeable. Good thinking, though...

The VMS would be the most efficient set up since it's a direct feed...

As stated it wont help with air feed to the CAI so much. I would redirect it to the engine bay itself to keep temp down on the motor. The 4.6 in the s197s heat soak bad at times depending on weather/driving conditions. Any way you can ventilate the air in the engine bay with cooler air is a good thing to do.
