Help IDing Plenum and TB
 

I bought my Cayman S thinking it had an IPD plenum. I replaced my AOS last night and instead it appears to have some stock parts cobbled together with a silicone elbow reducer. See attached for part numbers. I think its a 996 GT3 plenum and 4.5L cayenne turbo throttle body, but I'm having trouble identifying the part numbers. What do I have here?

You should post in the 996/997 forum. This forum is for air cooled cars.
Good luck.
