Official Porsche Online Parts Catalog (PET)
Porsche provides its own electronic parts catalog, known as PET (Porsche Electronic Parts Catalog). This is the same database used by dealerships and independent shops. It contains complete listings for all models from the 356 through the latest 911, Cayenne, Macan, and more.
Accessing PET for Free
Porsche does not publicly host a direct online portal for PET, but you can download the software for free from certain enthusiast sites. The official Porsche US website offers a parts lookup tool called "Porsche Parts & Accessories" where you can enter your VIN and browse parts. Alternatively, the PET application (Windows only) can be found on sites like Pelican Parts or through Porsche club forums. Once installed, you can navigate by model, engine, or category and print diagrams.
What You Get with PET
- OEM part numbers: Every original part has a unique number.
- Exploded diagrams: Visual breakdown of assemblies.
- Parts lists: Descriptions, quantities, and notes.
- Updates: The catalog is periodically updated; check for the latest version.
Third-Party Free Online Porsche Parts Catalogs
Several automotive websites offer free online catalogs specifically for Porsche parts. These are not official but they pull data from PET or other databases and present it in a user-friendly web interface.
Pelican Parts Catalog
Pelican Parts is a well-known Porsche specialist. Their website has a comprehensive catalog with diagrams and part numbers for most models. You can browse by vehicle (e.g., 1999 911 Carrera) and then by category (e.g., Brakes, Engine). The catalog is free to use, and you can see pricing and availability (but buying is optional).
AutoAtlanta
AutoAtlanta offers an online Porsche parts catalog for classic models, especially the 356 and early 911. Their site includes exploded diagrams and OEM numbers. Good for restoration projects.
ECS Tuning
ECS Tuning has a Porsche parts catalog that lets you search by VIN or year/model. While they sell parts, the catalog itself is free and useful for looking up numbers and diagrams.
How to Use a Porsche Parts Catalog Effectively
Search by VIN
Using your Vehicle Identification Number (VIN) is the most accurate way to find correct parts. Official and many third-party catalogs allow VIN search. This ensures you get parts for your exact year, model, and options.
Identify Your Part Number
If you have an old part, look for the Porsche part number stamped on it (typically 9-character format, e.g., 993.347.027.00). Enter that into the catalog to confirm fitment and see superseded numbers.
Read Diagrams Carefully
Diagrams show how parts fit together. Note references like "Item 12" that correspond to a list. Some catalogs let you click on the part to see more details.
Check for Supersessions
Porsche often updates parts. If your part number is superseded, the catalog will list the new number. Always use the latest version to avoid ordering outdated stock.
Tips for Finding the Right Porsche Part Online
Verify Compatibility
Not all catalogs are 100% accurate. Cross-reference with multiple sources. If the part appears in PET and a third-party site, it's likely correct.
Look for PDF Versions
Some online catalogs offer downloadable PDFs of entire sections. These are handy for offline reference. Owners' manuals and parts manuals are sometimes available through Porsche clubs.
Use Forum Resources
Porsche forums like Rennlist, Pelican Parts Forum, and Planet-9 have extensive discussions where members share part numbers and catalog tips. Search there before buying.
Final Recommendation
For most DIYers and owners, the best approach is to combine the official Porsche PET catalog (download free from enthusiast sources) with a reputable third-party online catalog like Pelican Parts. Use PET for exact diagrams and part numbers, and use the web interface for quick lookups when you don't want to run a Windows application. Always verify with your VIN and check supersessions. This combination gives you a complete, free Porsche parts catalog that will help you maintain, repair, or restore your car accurately.
