Cometic C4576-066 MLS Cylinder Head Gasket for Nissan SR20DE/SR20DET 87.5mm Bore

The Cometic C4576-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan SR20DE and SR20DET engines found in 1994-2002 vehicles. This gasket features an 87.5mm bore diameter and 0.066-inch compressed thickness, designed for rear-wheel-drive applications equipped with Variable Cam Timing (VCT).

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under high-compression and boosted conditions
• 0.066-inch (1.68mm) compressed thickness allows for precise compression ratio tuning
• 87.5mm bore diameter accommodates stock and slightly overbored cylinder applications
• Specifically designed for RWD SR20 configurations with VCT
• Engineered to withstand extreme temperatures and pressures in performance applications
• Eliminates the need for additional sealants when installed on properly prepared surfaces

Cometic MLS gaskets feature multiple layers of stainless steel with embossed sealing beads that allow the gasket to adjust to minor surface imperfections while maintaining consistent clamping loads. This makes the C4576-066 an ideal choice for both street-driven and track-focused SR20 builds, turbocharged applications, and engine rebuilds where reliability and performance are critical.
