Elring 738.320 is an exhaust pipe flange gasket built around precise sealing dimensions for BMW exhaust service. With a 55 mm inner diameter, 65.5 mm outer diameter, and 13 mm thickness, it is sized to support a secure seal at the flange connection on select BMW M3, Z4, and Z3 applications.

Key Features

• Part number 738.320 for direct identification and ordering
• 55 mm inner diameter for the exhaust passage opening
• 65.5 mm outer diameter for flange coverage
• 13 mm thickness for proper sealing compression
• Elring exhaust sealing component for flange-to-flange service
• Cross-reference: BMW 11 62 7 830 668 for the same application

Fitment and Application

• Fits 2008-2013 BMW M3, N/A

This exhaust pipe flange gasket is used at the joint between exhaust pipe sections where a stable seal is needed to manage exhaust flow and maintain connection integrity. The Elring 738.320 dimensions are important for BMW exhaust repairs because the inner diameter, outer diameter, and thickness must match the flange geometry to seal correctly. It is a practical choice for BMW M3 exhaust gasket replacement, BMW Z4 exhaust flange sealing, and BMW Z3 exhaust service when the original gasket is worn or compressed.

Common Issues It Can Address

• Exhaust leaks at the flange connection
• Noise from a failing exhaust joint
• Soot or residue around the pipe flange
• Loss of sealing after gasket compression or heat cycling
• Service replacement during exhaust pipe or flange repair

Installation Notes and Tips

Confirm flange dimensions before installation and compare the old gasket to the new Elring 738.320 part. Clean both mating surfaces thoroughly so the gasket seats evenly, and inspect the flange for warping, corrosion, or damage that could prevent a proper seal. Use the correct torque sequence for the exhaust fasteners and recheck the joint after heat cycling.

Quality Assurance

Elring is known for sealing components used in engine and exhaust service, and this gasket is built to match the specified BMW application dimensions. Verify the part number 738.320 against the vehicle and exhaust configuration before installation.
