Digging into my new project so I apologize for littering the board with questions. Looking at replacing a lot of hoses and other bits under the hood. I have noticed a lot of these are NLA. I am sure people here have found compatible parts and hoping someone can point me in the right direction. Don’t have a good way to post pictures so I guess part numbers may be the way to go.
Looking for:
93111037900 this is the sealing ring for the intake pipe to throttlebody

93111018501 this is an elbow not sure exactly what pipe it is for but it is basically gone on my car.

The first one is the outer black piece, not the red o-ring that does the actual work, right? I think it is primarily cosmetic. I was never able to find one and it didn't seem to matter. There are no vacuum leaks due to not having it fitted.

The second one I think is found in a few different places, right? I replaced the one for the recirc/blowoff valve thing on the turbo with some sort of right angle hose from the local auto parts store that I cut down to size. I believe there is a thread on here about some recommendations, which is what I followed.

Correct, it is just the black outer piece. Good to know that does not cause leaks. Anyone know of a good replacement to at least make it look good up there? Hose on the outside of the pipe and throttle body maybe?

Does anyone happen to know the id of the hose needed here? I don’t have a good hose to take for reference.

Maybe I am missing something, I got part numbers from the PET but where as all the bolt sizes are listed the hoses I am looking for just state moulded hose with no size provided. Am I looking in the wrong place?

Each of the hoses in the PET are listed with size information.

There are two size elbows used in this intake vacuum system, 18mm ID and 15mm ID.

Here's a thorough thread covering this part and all the other rubber elbows. One of the sizes is still available through Porsche, the other or both are available aftermarket. You'll need a handful of them -- if the one is disintegrated, just replace them all.

Thanks, I must be looking at a different version of PET. Good to know there are basically only 2 sizes.
