The factory put the valves in convenient locations. It still works, but not as efficiently. Jim, With the Tial you install the correct size spring that matches your engines vacuum, although it isn't 100% in all circumstances, it does limit the open times during deceleration. I'm not sure, but I think Tial is the only ones who offer different spring rates for their BOV's?
Gumba the best place on a 930 is the charge tube from the turbo to the intercooler. If you went a Tial for example, they can be ordered with a steel or aluminum bung for the valve.
