Manufactured from high-quality fuel-resistant elastomer, the O-ring is engineered to withstand constant exposure to petrol, high fuel pressures, engine heat and repeated thermal cycling without hardening, cracking or losing elasticity. Precision-sized to the original Porsche dimensions, it provides direct OE-style fitment and reliable sealing performance during injector installation, servicing or engine repairs.  

What This Product Does:

• Creates a leak-free seal around the fuel injector.
• Maintains correct fuel system pressure.
• Prevents fuel leaks between the injector and its mounting point.
• Helps prevent air entering the fuel system.
• Protects surrounding engine components from fuel contamination.
• Supports efficient fuel delivery and engine performance.
• Restores factory sealing performance.
• Forms an essential part of the fuel injection system.

Symptoms Of Wear Or Failure:

• Fuel smell from the engine bay.
• Visible fuel leaks around the injector.
• Difficult engine starting.
• Rough idle or engine misfires.
• Reduced engine performance.
• Increased fuel consumption.
• Loss of fuel pressure.
• Cracked, flattened or hardened O-ring.
• Fuel system fault codes.
• Increased fire risk due to fuel leakage.

Why Replacement Matters:

• The fuel injector O-ring is continually exposed to fuel, high operating temperatures and pressure fluctuations. Over time, the sealing material can harden, shrink, crack or become compressed, reducing its ability to maintain an effective seal around the injector.
• A worn or damaged O-ring can allow fuel to leak from the injector, reducing fuel system pressure and affecting engine performance. Fuel leaks within the engine bay also present a significant safety hazard and may damage surrounding components if left unresolved.
• Replacing the O-ring whenever a fuel injector is removed or serviced helps ensure a secure, leak-free fuel system. The genuine Fuel Injector O-Ring is manufactured to OE standards using premium fuel-resistant materials, providing factory-style fitment, dependable sealing performance and long-lasting durability, helping maintain the safety, efficiency and reliability expected from your Porsche.

The OE Match fuel injector seal ring set is for injector sealing repairs on Porsche 958 Cayenne and 970 Panamera 3.0L Hybrid applications. It contains three sealing rings for renewing the seals around an injector during appropriate repair or removal and refitting work.

Fits

• Porsche 958 Cayenne 3.0L HYBRID 2011–18
• Porsche 970 Panamera 3.0L HYBRID 2011–16
  
  Check fitment for your specific vehicle (model, year, engine) before ordering.
  
  Required Quantity

Six injector seal sets are required for the complete six-injector arrangement on the applicable 3.0L Hybrid engine.

What Is This Part?

This is a set of sealing rings used around a fuel injector in the petrol engine's high-pressure injection assembly. The injector sits between the fuel supply and the combustion chamber, with seals maintaining separation at its connections and seating points. These rings are service parts for the injector installation; they do not control fuel metering or correct an injector's electrical or internal mechanical faults. Renewing the appropriate seals is part of reassembling an injector correctly after a sealing repair or other work requiring its removal.

What Does This Part Do?

• Seals injector interfaces: The rings form seals at the injector's designated sealing points.
• Maintains separation: Correctly seated seals help prevent leakage across the interfaces they are intended to seal.
• Supports injector refitting: Replacement rings allow damaged or disturbed seals to be renewed during reassembly.
  
  Why Replace This Part?

Injector seals may need replacing when inspection finds cuts, flattening, distortion or other deterioration that prevents correct seating. Heat exposure and removal or installation can affect sealing condition, so the rings and their mating surfaces should be checked whenever the injector is disturbed. Follow the engine-specific repair procedure for seals that must be renewed after removal.
A sealing repair should follow diagnosis of the actual leak. Fuel odour, rough running or starting difficulties can have several causes, including injector faults, fuel connections and ignition problems. New seals will not repair a damaged injector body, worn sealing seat or defective fuel line.

When to Replace This Part?

• Visible seal damage: A ring is split, nicked, distorted or no longer seats correctly.
• Confirmed leakage: Inspection identifies leakage at an injector sealing interface.
• Removal damage: A seal is damaged while extracting or refitting an injector.
• Specified renewal: The relevant workshop procedure requires new seals after injector removal.
• Repeat sealing trouble: Inspect the injector, sealing grooves and mating surfaces before fitting another set.
  
  Where Is This Part Fitted?

Location: Around the petrol engine's high-pressure fuel injectors, at their sealing interfaces within the fuel rail and cylinder-head installation.

Technical Details

• Number of sealing rings: 3.
