I like your "catch can". It also seems you have the updated valve cover? If so, what's the benefit over the old one (if you happen to know how the old one is)? I have the old config with both valves on each cover.
Also, if you have the updated cover, does only 1 have a valve (driver side)?
I am not sure if I want to change to the updated design & winter setup. The cost is quite high even for only 1 cover. Plus the hoses.
