Hood deflectors are no bueno for turbocharged vehicles with hoodscoops. It causes the air to flow up OVER the scoop. Not all of it, but a lot of it. The car won't perform as efficiently. I really wanted it for my 08 Forester Sports XT since I think they help that car to look good.
When I bought the WRX in August of 2010 there was a lot of drama. I didn't have $1k to get the whole front end clear bra'd. With my next car it's definitely getting done, though.
Despite getting compliments on the DGM all the time from people of all types, my next car is going to be black. I had it on my 01 2.5RS and I just loved it. I wash my car all the time anyways and I plan on using the Turtle Wax Black Box kit often to keep the car clean. I'mma OD on this cleaning obsession I'm going to develop, full comatose state.
