You'll have to do some adapting - the Wilwood (and other aftermarket) valves are 1/8NPT fitting, while the VW lines use metric bubble flare. Depending on where you want to mount the valve you may have to install some new metric hard lines - or else try and splice it into an existing line?
CNC and others make the metric to NPT adapter fittings.
