I noted on the other Focus site that someone pulled back the shroud on an ST and it doesn't have the snorkel...just the air intake on the radiator support like ours. The air box is the same apparently so this gives weight to the fact that this piece doesn't serve a major purpose other than possibly noise reduction (man...wouldn't it be nice to talk to the engineers at Ford sometimes with questions like this?). Again, gives me some confidence that this is an "ok" mod to do and will not screw anything up. I am not planning on touching the shroud underneith..the ST still has it so how bad can it be? More driving today....sure feels better to me w/o the snorkel...not sure how to describe it but maybe better throttle response captures it.
If its not grown it's mined!
