About Cometic Gasket

Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.

Precision Sealing for BMW S50/S52 Engines

The Cometic MLS (Multi-Layer Steel) Head Gasket is engineered for the high-revving US-spec S50B30 and S52B32 engines found in the iconic BMW M3 and Z3 M models. With a compressed thickness of 0.070 inches and an 87mm bore, this gasket provides the perfect seal for engines pushing beyond factory specifications. The multi-layer stainless steel design offers superior structural integrity and rebound characteristics, ensuring your engine holds up under the most demanding conditions.

Key Features and Benefits

  • Compressed Thickness: 0.070 inch
  • Bore Size: 87mm
  • Material: Multi-Layer Stainless Steel with Viton Coating
  • Compatibility: US-Spec BMW S50/S52 M3 and Z3 M
  • Performance: No sealant required for installation

Each gasket features an advanced Viton fluoroelastomer rubber coating on both sides, which is heat-resistant up to 250°C (482°F). This coating conforms to the surface of your cylinder head and block, creating a robust seal that resists corrosion and thermal stress. Whether you are building a track-focused M3 or a high-performance Z3 M, this gasket provides the peace of mind you need to push your engine to the limit.
