Its really easy. There is a small nut on the under side of the hood closest to the windshield. Just loosen that first, then there are clips holding from the front side of the vent and 3 on each side. Don't force it too much but they come out with no problems.
Carbon fiber hood vents by TruCarbon. Old vents came out easier after I removed the hood insulator. The bolt is a 9mm btw. Job only takes about 20 mins even if you take your time. Difficulty level novice.
