Don't know how it works. I think it is just a stronger spring that keeps the pressure relief valve more closed. The one I bought has two springs, for a dual relief case. I have that they definitely will work. In fact the VW expert here, told me that it should take my pressure from the 27 or so that I am getting, up to over 40. If so, I am good to go, and will do a little more work to try to get the oil temps down.
I also have cool air on the sump, but I can't let it flow, because that is also where I get the fresh air inlet for my carbie.
