Very straight forward install; took me about 1 hr including the aFe Throttle Body spacer. The rubber seal was a little finicky, and it took a lot more effort than expected to align with the factory air box. I also broke a hose clip, which I admit was user error, but that made the install much harder than it would have been. Sound has a low howl, but not too aggressive. Mine also has a slight whistle when shifting, similar to a blow off valve, but I attribute that more to the throttle body spacer than the CAI.
