The factory twin turbo wing may look simple from the outside, but underneath it is compose of many unusual expensive parts and pieces. I was lucky enough to find a used factory twin turbo wing for sale, but unfortunately when it arrived I realized that it was missing all the mounting hardware, the inner grille and other parts and pieces. So I obtained a copy of the factory Porsche component break down sheet to see what parts and pieces are in the factory twin turbo tail.
To my surprise the all the parts and pieces came out to $170, and the inner grille by itself was $320.
Here is a list of the parts I purchased
