"redesign" and fitment issues. The nubs that the IC ducts mount to have been shaved/cast flush with the IC so you either have to go with some sort of spacers, OR bend the crap out of the IC ducts to get them screwed on. I *think* this may be why BOTH of my ducts are high. One is completely above the bottom IC slit, the other not so much. My friend's didn't have this problem, but he also got his when they were first introduced.
p.s. I did trim back the duct as instructed. Also, I do agree that the price is VERY appealing.
