Im looking to buy the cx racing h/e. I was wondering If I need the dual pass+B also. Does the dual pass replace the single inlet of the h/e or what?

 

you dont have to have the cx to run the dual pass and vise versa. the dual pass just reroutes your coolant in your intake manifold. the option b is a an extra tank to supply fresh coolant. it replaces your old fill neck too.

 

so I am still able to purchase al of these at the same time? I just wanted to make suse I wasnt buying something that the cx come with or somethin
