2006 Porsche 997 Used Parts: A Complete Guide to Finding Quality Components

When your 2006 Porsche 997 needs a replacement part, buying new from a dealer can be expensive. Used parts offer a cost-effective alternative, but you need to know what to look for. The 997 generation (2005–2008) is known for its reliability, but certain components wear out or fail over time. This guide covers the most commonly replaced used parts, where to find them, and how to ensure you get a quality piece that will last.

Common 2006 Porsche 997 Parts That Fail or Wear Out

IMS Bearing and RMS

The intermediate shaft (IMS) bearing and rear main seal (RMS) are notorious failure points on the M96 and M97 engines used in the 997. For 2006 models, Porsche updated the IMS bearing to a larger, more durable design, but failures still happen. If you're buying a used engine or need these parts, look for ones that have already been upgraded to a ceramic hybrid bearing. Avoid cheap aftermarket copies. A used engine with a documented IMS replacement is a safer bet.

Water Pump and Thermostat

The water pump on the 2006 997 is a common failure item. Plastic impellers can crack, leading to overheating. Used water pumps are risky unless you can verify they were replaced recently with a metal-impeller version. Similarly, the thermostat housing often cracks. Only buy used thermostat housings that show no signs of corrosion or cracking.

Coil Packs and Spark Plugs

Ignition coils fail relatively often, especially if the original spark plugs were not changed on schedule. Used coil packs are inexpensive, but test each one with a multimeter for proper resistance. Avoid coil packs with cracked boots or oil contamination. Spark plugs are cheap new, so used ones are not recommended.

Suspension Components

Control arms, bushings, and sway bar links wear out. Used OEM control arms can be a good deal if the bushings are still in good shape. Inspect the rubber for cracking or sagging. The 997 uses aluminum control arms that can last a long time, but the ball joints eventually get loose. A used arm with tight ball joints and intact boots is fine.

Brake Calipers and Rotors

Brake calipers often seize from lack of use or old fluid. Used calipers are acceptable if they have been professionally rebuilt. Check for torn dust boots and smooth piston movement. Rotors should be replaced new due to safety concerns, but used Porsche rotors can be okay if they measure above minimum thickness and have no cracks. Slotted rotors are not recommended used.

Interior Parts

Climate control units, window switches, and seat mechanisms can fail. These are straightforward to replace with used parts. Look for units with no broken tabs or faded displays. For the PCM (navigation screen), used units from the same production year avoid compatibility issues.

Where to Buy Used Parts for a 2006 Porsche 997

Specialty Porsche Recyclers

Companies like Porsche of the Main Line (used parts), LKQ, and others dismantle wrecked cars. They often warranty parts for 30 to 90 days. This is the most reliable source because they inspect and test parts before selling. Expect to pay a premium over generic junkyards, but you get peace of mind.

Online Forums and Classifieds

Forums like Rennlist, Pelican Parts, and 6SpeedOnline have classified sections where owners sell parts. This is great for rare items (e.g., GT3 wings, special wheels). Risks include lack of returns, so communicate clearly and ask for detailed photos. Payment via PayPal Goods and Services offers some protection.

eBay (But With Caution)

eBay has a vast selection of used 997 parts. Filter by “used” and check seller ratings. Look for listings with multiple photos and a clear description of condition. Message the seller about warranty and return policy. Avoid sellers with zero feedback or vague descriptions like “ran when pulled.”

Local Junkyards

Some self-service junkyards have German cars, but the 997 is not common. You might find one under “premium” inventory. Bring tools to remove parts yourself. Check the car’s VIN to ensure the part is compatible. Beware of water damage or accident cars.

Buying Tips to Avoid Problems

• Always verify part numbers. The same year 997 has different versions (Carrera, S, 4S, Turbo, etc.). Use the VIN to cross-reference.
• Inspect wiring and connectors. On electronic parts, bent pins or corrosion can cause intermittent issues.
• Check for leaks. Used engines, transmissions, and A/C compressors may leak. Ask for pressure test results.
• Prefer parts with a warranty. Even 30 days gives you time to test the part.
• Keep your old part. If you return a core, you might get a discount. But also, having the old part helps measure new one.

Recommended Parts to Buy New vs. Used

| Part | New Recommended? | Used Acceptable? | Notes | |------|-----------------|------------------|-------| | IMS bearing | Yes (upgraded kit) | No | Critical; failure destroys engine. | | Water pump | Yes (metal impeller) | Risky | Only if confirmed recently replaced. | | Coil packs | Used okay | Yes | Test resistance. | | Brake rotors | Yes | No | Safety issue. | | Suspension arms | Used okay | Yes | Inspect bushings and joints. | | Interior trim | Used okay | Yes | Cosmetic only. | | Engine block | Used okay | Yes (with inspection) | Check cylinder bores for scoring. |

Final Recommendation

For most 2006 Porsche 997 used parts, buy from a specialized Porsche recycler that offers a warranty. Avoid critical engine internal parts (IMS bearing, water pump) unless you can verify a recent upgrade. For interior items, suspension components, and electronics, used is a safe bet if you inspect carefully. Always know the exact part number needed for your VIN. Remember, the goal is to save money without compromising reliability. A well-maintained used OEM part often beats a cheap new aftermarket part. Take your time, ask questions, and you can keep your 997 on the road for years without breaking the bank.
