They are great on the move and look great under the bonnet, I spaced mine slightly away from the slam panel as I felt that sitting flush it wasnt getting enough air and slight suffered at slow speeds under hard accleration.
Hard to see the gap between the scoop and the slam panel from this angle, but its there. Compliments the bay nicely tho
I could have butchered my slam panel to allow more air in but didnt feel it was worth it
