Precision Sealing for Left-Bank Coyote Performance

The Cometic 94.5mm Bore .040in MLS Cylinder Head Gasket is the premier choice for your Left Hand Side (LHS) cylinder bank on the Gen-3 Ford 5.0L Coyote engine. Designed to handle the rigors of high-performance driving, this gasket ensures your engine maintains optimal compression under the most demanding conditions.

Engineered for Extreme Environments

Constructed from multiple layers of stainless steel, this gasket is built to resist heat, corrosion, and the mechanical stress of high-RPM operation. The embossed outer layers feature a specialized Viton rubber coating, which conforms to cylinder head and block surfaces to create an airtight, leak-proof seal even in engines with modified surface finishes.

  • Optimized Thickness: .040in thickness helps maintain precise quench and compression ratios.
  • Stainless Steel Construction: Superior strength and rebound properties for long-term reliability.
  • Thermal Resilience: Viton coating handles temperatures up to 482°F.
  • Vehicle Fitment: Compatible with 2018-2023 Ford Mustang GT, Bullitt, and GT Premium.

Don't let a failing gasket compromise your engine's power. Whether you are performing a routine rebuild or a full performance upgrade, rely on the proven engineering of Cometic gaskets available through GGCRACING.
