If you look at my pic, on the right side of the opening in the bra there's a square of material that is velcroed in place. I made it "just in case" I needed more cooling - makes me feel like a highway trucker with all the fabric variable grille blocks I see running down the road on those rigs.
But I've never opened it. In fact, I've since blocked the small upper opening between the hood and bumper as well.
Of course, YMMV, since your engine is a bit bigger and may need more cooling than the 1.0L.
