Where does this part go?

Recommended Posts

Can someone tell me where this attaches and where the two vacuum lines go? I have a 99 996 C2. Thanks

Secondary Air Injection system changeover valve, and the little hoses insert into the intake resonance tubes. That's my guess. It has a part number R99660512301. Does your part have a P/N? Might help. Good source for looking up parts: http://www.autoatlanta.com/porsche-parts/911.php

Mine is part # 993.605.123.00. I need to know where the change over valve mounts and where the two lines hook up. Thanks

look at attached pictures. this is on a 1999, carrera cabrio, six speed I am assembling. your part mounts on front left intake manifold bracket. and the vac hoses go the rear of engine; one connects to the black cannister 'spider" and the other to the flapper on the rear intake runner.

good luck
