Chasing a P0171 and P0174 vacuum leak. What's a good place to get Jag parts online? Auto Parts Warehouse?

Also, is there a good resource to pull up OEM part numbers so I can just search for them online? For example, the large diameter (4"??) short crinked tube from my air filter casing to the MAF sensor looks pretty brittle. I wanted to replace it (in addition to the IMT Orings and the PVC breather hose), but I can't find that part online since I don't know what it's called or what the part number is.

 

For part numbers download the JTIS & JEPC from the forum.
For OEM parts try Direct JPLV Porsche Parts.com.
They are a forum sponsor. RockAuto is also a good source.

 

I use both, Gaudin and https://oemdiscountcarparts.com/

 

Thanks. I checked out the Gaudin site and got a few parts. I was unable to find the crinkled air tube, the PCV breather hose, and the IMT Orings on the website. Where can I get those?

 

The air tube is part of the air cleaner assemble. I don't think its an individual part.

 

Here's the crankcase hose.
Don't know about the IMT O rings.
