Porsche 928 Parts Catalogs & Advice

Restoring a Porsche 928 requires sourcing high-quality parts, and fortunately, several reliable options exist for securing everything from mechanical components to interior trim. Popular avenues include specialized Porsche suppliers, online marketplaces, classic car salvage yards, and Porsche enthusiast forums.

Specialized Porsche parts suppliers, such as Pelican Parts, AutoAtlanta, Sierra Madre Collection, and Stoddard, provide authentic and reproduction parts specifically tailored for Porsche restorations. These sources typically offer detailed product descriptions, part numbers, and technical support, helping to ensure authenticity and fitment.

When buying Porsche 928 parts—particularly online—careful consideration is essential. Always verify the reputation of the seller or platform, read customer reviews, and confirm that the parts are genuine, OEM-quality, or high-quality reproductions. Pay close attention to return policies and warranty information, as restoration parts may require returns if fitment issues arise. Additionally, ensure compatibility by double-checking part numbers, diagrams, and cross-referencing with Porsche documentation or expert advice.

Lastly, authenticity and originality significantly affect the value and authenticity of your Porsche 928 restoration. While aftermarket or reproduction parts can offer cost savings, maintaining originality with OEM or NOS (new old stock) parts is typically favored for maximum resale value and authenticity among collectors.

The Porsche Parts Diagrams (PET) is an official Porsche electronic catalog containing detailed exploded-view diagrams and comprehensive part listings for Porsche vehicles, including the Porsche 928. PET stands for Porsche Ersatzteile Teilekatalog, or in English, Porsche's official parts catalog.

For a Porsche 928 owner or restorer, the PET serves as an invaluable reference guide, clearly illustrating each individual component within assemblies and showing how parts fit together. Each component in these diagrams is assigned a unique part number, making it easy to identify, source, and order the correct replacement parts.

PET is structured into clear sections covering the entire vehicle—from engine, suspension, and braking systems to interior trim, body panels, and electrical components. For anyone restoring a Porsche 928, consulting the PET helps eliminate confusion, verify compatibility, and ensure authenticity of the parts selected.

In short, the PET diagrams are indispensable resources for Porsche 928 enthusiasts, restorers, and mechanics, providing clarity, accuracy, and confidence throughout the restoration and maintenance process.

Yes, there are several effective ways to confirm you're purchasing genuine Porsche 928 parts:

1. Verify the Porsche Part Number:

• Porsche parts are identified by unique part numbers, listed clearly in the Porsche PET diagrams.

• Ensure the part number matches the official PET diagrams provided by Porsche or trusted suppliers. Genuine Porsche parts typically have this number stamped or labeled on the packaging or the component itself.

2. Check Packaging and Labeling:

• Genuine Porsche parts often come in distinctive Porsche-branded packaging.

• Look for holograms, logos, or official Porsche seals on boxes or labels. The packaging should clearly state “Genuine Porsche Part” and include a Porsche part number.

2. Source from Authorized Porsche Dealers or Specialists:

• Purchasing directly from authorized Porsche dealers, Porsche Classic partners, or reputable Porsche restoration specialists significantly reduces risk.

• Reliable sellers will explicitly indicate authenticity, and often provide documentation or certification to support it.

3. Examine Product Quality and Fitment:

• Genuine parts typically exhibit excellent fit, finish, and craftsmanship.

• Poor fitment, incorrect dimensions, or inferior materials are signs that a part is likely aftermarket or counterfeit.

3. Request Documentation or Receipts:

• Genuine Porsche parts generally include documentation (receipts, invoices, certificates) confirming authenticity.

• Keep these documents, as they add value and credibility during restoration and future resale.

4. Cross-Reference via Porsche PET Diagrams:

• Cross-reference the provided part number against the Porsche PET (Parts Diagrams) catalog. The PET system is your best official reference to validate authenticity.

• If the seller cannot provide the Porsche-specific part number or avoids providing this information clearly, approach with caution.

4. Inspect Markings and Logos:

• Authentic parts often feature clearly stamped or embossed Porsche logos, part numbers, and sometimes production date stamps.

• Poor-quality markings or absence of identifying stamps usually indicate aftermarket or counterfeit components.

Quick Checklist Before Buying:

• Part Number Validation: Confirm the part number matches official Porsche PET diagrams.

• Seller Reputation: Trusted Porsche suppliers and dealers have track records and online reviews.

• Documentation: Always request and verify authenticity documentation.

• Visual Inspection: Confirm correct branding and quality indicators on the part and packaging.

• Seller Reliability: Buy from well-known, reputable Porsche specialists or dealers whenever possible.

Taking these steps will significantly increase your confidence that the Porsche 928 parts you're purchasing are genuine and appropriate for your restoration.

Buying Porsche 928 parts on eBay or Facebook Marketplace can certainly be viable, especially for rare or hard-to-find items. There are even several Porsche 928 specific groups on Facebook worth checking out. However, extra caution is necessary because authenticity can vary significantly on these platforms. To minimize risk, always carefully research the seller's reputation by reviewing their feedback ratings and history on eBay or their profile and previous listings on Facebook Marketplace. A seller specializing in Porsche or classic-car components who has positive feedback from previous buyers is a safer choice than someone unfamiliar with Porsche parts. Where you can, focus on existing, big Porsche 928 groups on Facebook, where you know likeminded folks congregate, not just for the advice but as a way to vet anybody selling parts there.

Additionally, request clear, detailed photographs of the parts, focusing especially on any stamped or embossed Porsche logos, part numbers, date stamps, and packaging. Ask for documentation such as original receipts, invoices, or certificates that prove authenticity. If possible, arrange an in-person inspection—particularly important for high-value parts like engines, transmissions, or rare interior trim. Consider consulting knowledgeable Porsche communities online or local Porsche clubs to confirm authenticity if you're unsure.

Finally, always use secure payment methods that offer buyer protection, and avoid sending direct, unprotected payments like cash, wire transfers, or unsecured apps. Using platforms like PayPal, which offer dispute resolution, can add an extra layer of safety. By taking these precautions, you can confidently source genuine Porsche 928 parts from platforms like eBay or Facebook Marketplace.
