Extended Product Information

FAQs

What material is the Febi Bilstein 174303 seal made from?

The seal is made from PTFE (polytetrafluoroethylene), a high-performance plastic known for its excellent resistance to heat, chemicals, and friction.

What vehicles is this injector seal compatible with?

It is compatible with a range of BMW models including various 1, 3, 5, 6, 7 Series, X6, and Z4 models. It's crucial to verify compatibility with your specific vehicle's engine and chassis codes.

How do I know if I need to replace my injector seals?

Symptoms include fuel smell, rough idling, reduced engine power, poor fuel economy, or diagnostic trouble codes related to fuel system leaks or injector performance.

Can I install this seal myself?

Yes, if you have mechanical experience and the necessary tools. However, improper installation can lead to leaks or engine issues. Refer to a vehicle-specific service manual for detailed instructions.

What is the difference between this seal and other injector parts?

This is a specific seal ring designed to create a tight fit for the fuel injector within the engine. It is not the injector itself, nor is it a bracket or connector, but a critical component for sealing.

Does the seal require any special preparation before installation?

Typically, the seal should be installed dry or with a minimal amount of approved lubricant to aid seating. Avoid excessive lubricant or incompatible substances that could degrade the PTFE material.

What are the key dimensions of this seal?

The seal has an Inner Diameter of 6.4 mm, a Height of 2.8 mm, and an Outer Diameter of 8.1 mm.

Troubleshooting

Fuel leak detected around the injector after installation.

The seal may not have been seated correctly or may have been damaged during installation. Remove the injector, inspect the seal and seating area for damage or debris, and reinstall carefully, ensuring the seal is properly seated.

Rough engine idle or poor performance persists after replacing the seal.

The issue might not be related to the seal. Check for other potential causes such as vacuum leaks, faulty spark plugs, or issues with the injector itself. Ensure the seal was the correct part for the vehicle.

Difficulty installing the seal onto the injector.

Ensure you are using the correct seal for the injector model. If the seal feels too tight, check for obstructions or try a very small amount of compatible lubricant as per service manual recommendations. Do not force the seal, as it can be damaged.

Setup, Compatibility & Care

Setup:

  1. Verify Compatibility: Before installation, confirm that your vehicle's make, model, year, and engine specifications (including TecDoc Engine Numbers 20844, 27482) match the compatibility list provided for part number 174303.
  2. Clean Seating Area: Ensure the injector and the injector bore in the cylinder head are clean and free from debris, old seal material, or damage.
  3. Lubrication (Optional): A small amount of appropriate lubricant (e.g., silicone grease or injector lubricant) can aid installation, but consult your vehicle's service manual.
  4. Installation: Carefully place the seal onto the injector, ensuring it is seated evenly and correctly within its groove. Avoid stretching or distorting the seal.
  5. Reassembly: Install the injector into the cylinder head following the manufacturer's torque specifications and procedures.

Compatibility:

This seal is specifically designed for certain BMW models, including:

  • BMW 1 Series (E81, E82, E87, E88)
  • BMW 3 Series (E90, E91, E92, E93)
  • BMW 5 Series (E60, E61, F10, F07)
  • BMW 6 Series (E63, E64, F12, F13)
  • BMW 7 Series (F01, F02, F03, F04)
  • BMW X6 (E71, E72)
  • BMW Z4 Roadster (E89)

Refer to BMW part number `13537584315` for cross-referencing. Always double-check fitment with your vehicle's VIN or a reputable parts catalog.

Care:

As a static seal, this component requires no regular maintenance. Its care is primarily during installation to prevent damage. The PTFE material itself is highly resistant to degradation from fuel and heat, so its lifespan is dependent on proper installation and the operating conditions of the engine.
