I did it !
 

I replaced the airbox in one day without droping the engine. It wasn't hard but it was time consuming. 12 hous plus.:D

I will post pictures soon.

P.S. The problem I encountered !!! the parts guy from the porsche dealer gave me the wrong intake manifold gaskets. So I had to use the old ones with a gasket sealer silicone cement.:mad:

I runs fine now !

Now I have to track down that fuel smell which I suspect is between the tank and the rear mounted fuel pump. Any ideas ?

Way to go!!!
