Wiseco W6172 Nissan SR20DE MLS Cylinder Head Gasket

The Wiseco W6172 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for the Nissan SR20DE engine. Designed to meet the demands of serious performance builds, this gasket delivers a reliable, long-lasting seal where factory units fall short.

Key Features:

• Multi-Layer Steel (MLS) Construction: A high-pressure steel laminate design provides exceptional resistance to the intense shear forces generated between dissimilar metal pairings such as aluminum heads and iron blocks.
• Heat-Activated Embossments: Internal embossments expand under heat to create a progressively tighter combustion seal as engine temperatures and pressures rise — critical for high-output applications.
• Forced Induction & Power-Adder Ready: Purpose-built to hold up under the extreme combustion pressures and temperatures associated with turbocharged, supercharged, and nitrous oxide applications.
• Precision Fit: Engineered to exact specifications for the SR20DE, ensuring proper sealing without the need for additional sealants.
• OEM Upgrade: Surpasses factory head gasket performance and durability, making it an ideal replacement for high-performance builds.

The Wiseco W6172 MLS head gasket is the trusted choice for SR20DE engine builds demanding consistent sealing performance under race-level stress. Backed by Wiseco's decades of experience in high-performance engine components.
