2X Entries For Our 25th Anniversary Sweepstakes!

When tearing down your BMW’s M54 engine for a top-end refresh, doing the job once and doing it right means refreshing all your critical seals at the same time. This premium Engine Cylinder Head Gasket Set from Elring is engineered to restore factory-level sealing, preventing costly oil and coolant leaks while locking in factory compression. Elring is a trusted global OE manufacturer for European makes, ensuring that every seal and component fits exactly like the factory intended.

This comprehensive kit provides an all-in-one solution for servicing the cylinder head on your early 2000s 3 Series, 5 Series, Z3, or X5. Please note that this is a supplementary valve regrind set and does not include the primary head gasket itself, allowing you to select the precise head gasket thickness required for your specific engine machining needs.

Key Features

  • OE-Quality Engineering: Manufactured by Elring, an original equipment supplier trusted worldwide for precise European automotive sealing.

  • Comprehensive Top-End Refresh: Provides all necessary supplementary seals and gaskets for a thorough valve regrind or cylinder head service.

  • Enhanced Component Value: Contains more individual sealing articles than the basic factory BMW OE kit.

  • Valve Stem Seals Included: Packed with high-grade valve stem seals to restore proper oil control in the valve train.

Specifications

  • Brand: Elring

  • Part Number: 903.340

  • BMW OE Reference Number: 11127507597 (11 12 7 507 597)

  • Kit Contents: Supplementary cylinder head gasket set with valve stem seals (excludes primary cylinder head gasket)

  • Engine Compatibility: BMW M54 2.2L, 2.5L, and 3.0L Inline-6 (Up to 09/2002 production date)
