Being able to lift the rear deck sounds like a good, practical attribute. I know I'd be more tempted to try something like this if I didn't have to remove it every time I opened the engine cover. It also gives you more options for the fixing hardware and the chance to hide most of it under the deck. I wonder if a taller, narrower "mouth" wouldn't provide better flow into the "neck" of the air scoop, but I'm probably just picking nits. I think it looks promising.
