I installed my intake this past weekend. The install for the Corksport intake was a breeze! The removal of the stock, whole different story... the rubber-ish sleeve that connects the air box to the throttle body was annoyingly difficult to remove. Go fig.
So far, here is what I like. The car does seems to have a bit more kick to it and I did notice my mileage has improved slightly. FYI - For my comparison, I made a note of the last time I filled the car up on stock intake and filled up the car with the SRI and saw I was able to get a 1 or 2 more miles per gallon so far. I'll do some more long term research and get back to you folks.
The one thing that can be unnerving at first is the occasional diesel like noise, but as Corksport stated the stock box is all about noise control, not optimal power. So it is a given to hear some of the noise depending how the throttle is applied. Nothing too annoying but you do notice it.
Overall, I would say this is a worthwhile mod for any 3 SKY owners.
