Key Features & Benefits

• Multi-Layer Steel (MLS) Construction — Three-layer stainless steel design provides superior combustion sealing, dramatically outperforming traditional composite gaskets under high heat and pressure cycles.
• Precision 79mm Bore Size — Matches the factory RB20 bore diameter exactly, ensuring a perfect seal from day one with no trimming or modification required.
• 0.051" (1.295mm) Compressed Thickness — Maintains optimal compression ratio for stock and mildly modified RB20 builds, helping preserve engine efficiency and power output.
• Embossed Stainless Steel Stopper Layer — The proprietary embossed sealing bead around each bore creates a high-pressure seal that conforms tightly to machined head and block surfaces.
• Reusable Surface Coating — Micro-encapsulated polymer surface coating eliminates the need for additional sealants and allows the gasket to conform to minor surface imperfections for a leak-free seal.
• High-Temperature & Boost Resistance — Engineered to withstand extreme combustion temperatures and elevated cylinder pressures, making it ideal for turbocharged RB20DET applications.
• Fits Multiple RB20 Variants — Compatible with naturally aspirated RB20E, dual-cam RB20DE, and turbocharged RB20DET engine configurations for maximum versatility.
• USA-Made Quality — Manufactured by Cometic Gasket in the USA, a trusted name in OEM-replacement and performance engine sealing since 1989.
