We are glad you like and thanks for posting the photos.
We designed this part originally for the Focus RS and RS 500. It was part of our MR375 package so it will handle significant flow.
Fortunately, the C346ST uses the BorgWarner turbo with mechanical recirculation valve so this part was compatible.
I will talk to engineering and see if there are any specific ratings.
As a side note, our new lower IC pipe upgrade helps turbo response and is an easy install once you are underneath the car.
We will be adding a kit with favorable pricing to the website that includes the pipe and bypass valve later today.
