Key Specifications

· Engine Compatibility: BMW S58B30T0 (3.0L Twin-Turbo I6).

· Bore Size: 85mm.

· Material: Multi-Layer Xtreme (MLX) Stainless Steel.

· Replacement Part Number: Replaces BMW OEM #11-12-8-088-729.

Performance Advantages

· Stopper Technology: Features a specialized "fold-over stopper" layer that provides a torque-limiting surface to prevent combustion seal yielding.

· Advanced Coating: Embossed outer layers are coated on both sides with Viton (a high-temperature fluoroelastomer), ensuring a micro-seal against fluids.

· Increased Seal Height: The multi-layer spring construction compensates for head lift during extreme cylinder pressures.

· Dry Installation: Designed to be installed dry; proprietary coatings eliminate the need for additional sealants or re-torquing.
