The vent on the hood is the real thing. Under that vent theres about a 1 foot cut out going into the engine bay. I assure you it's not a stick on. When i first bought the car i just had a p flow so i wanted a little more cold air. But now just for looks because i have a cai. As for the discs it's something i know is stupid but looks good. I was tired of painting my rusted drums every year.
