Hi,
In case anyone is considering adding a front air deflector to his journey, don't make it install at the dealer (unless you're really bad with tools).
They charge about 100$ + tx for that and it took me about 20 minutes by doing it really carefully. For sure you will need to drill 4 holes on the inside of the hood but it ts done easily.
By the way, I strongly suggest to install a deflector, after only 2 months I already had 3 rocks chips on my hood.
If anyone have any question on the procedure, just ask!
