Well, just for shits and giggles, I would drill a small hole in the center of that 'nipple' and hook up another hose to the windshield washer system.
Then, every time I activate the w.w. system it would also shoot a Pi__ stream out the front of the vehicle....

Just a thought..... (Yeah, I know... scatological humor)

Also, do the two matte black plastic "eyebrow" cover panels above the air intake grills on the right and left side of the front of the vehicle bother anyone else besides me? It is a rather cheap looking detail that detracts from what otherwise is a very attractive and aggressive front end design, IMHO. They look like an after thought, add-on.
