I don't believe the catch can is absolutely necessary with or without the K&N. I installed the catch can because I liked the concept. The interesting thing is that after a couple of thousand miles I have knocked out a quantity of condensed oil in the order of magnitude of a teaspoon or two. The oil drained from the catch can was reasonably clean, with no visual signs of contaminants. This does not mean that they do not exist, only that I could not detect them. Without a catch can I am not certain what length of time, or number of miles driven, is required before deposits build to such a point that performance of the car is actually reduced. So, if you have some money to burn and like the looks of the catch can, go for it. Otherwise, I do not know that I would worry about it. If anyone else has an opinion, feel free to interject.
