   The engine breather should be plumbed in to the inlet as per the standard car. Race cars with radical engines will often use a oil separation tank as the engines are that mad they actually start coughing up oil. Some cheap inductions kits don't have any of this. The engine still has to breath though so what some people do is stick crank case breather filter on the engine. Its not ideal and not even strictly road legal on modern cars.

   Is it best to run an oil breather filter then, or plumb it into say the green cotton raceland kit that I have?

    Officially no. Doesn't stop the majority of people doing it, and it doesnt fail the MOT either.

    The down side is the small amount of gas the engine is sucking in form the bottom end is warm and contains slightly less oxygen. The up side is you get a slight vacuum in the bottom end. End result is nether hear nor there for the most part.
    
    Though if you do go for the filter be positive to not let it get clogged up with oil as this will lose you power and generally end with your dip stick flying out and all your engine oil spurting out after it.
