K&N is currently in the R&D phase of production...so it might be another month at the earliest, but they are not making a true Cold Air...its actually going to be a Short Ram Air w/ Heat Shield...I believe Steedas is the same....so I dont think that will make a difference in chosing...both are great, dont have numbers from K&N yet to compare so couldnt tell you but I would imagine that either way it goes it would be very marginal in the difference...cost too. But Steedas is out if you dont want to wait...K&N might also eventually come out with an actuall cold air extension, where I dont believe Steeda would be in the market to do this....at least I havent seen it yet...so you will get more options from K&N.
