I did an ebay tube with the breather hole welded shut and the ends rounded out with a pipe expander because they were a little off round, Bpi flowstack with K&N filter, and an ebay catch can to deal with the valve cover breather with a K&N breather filter, I also replaced the shitty ebay coupler with a quality piece. The whole thing probably cost me like $120. I would not just buy an ebay intake and use it as is. I might also route the block breather into the catch can instead of the intake manifold, I just have to do some research to figure out if it is dependent on manifold vaccuum to work.
