Cometic C4283-092 MLS Cylinder Head Gasket for Nissan SR20DE/SR20DET

The Cometic C4283-092 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for 1994-2002 Nissan SR20DE and SR20DET engines in rear-wheel drive applications with Variable Cam Timing (VCT). This precision-manufactured gasket features an 88.5mm bore diameter and 0.092-inch compressed thickness, providing optimal sealing for both naturally aspirated and turbocharged SR20 applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 0.092-inch (2.34mm) compressed thickness allows for precise compression ratio tuning
• 88.5mm bore diameter engineered for stock and mildly overbored SR20 engines
• Designed specifically for RWD applications with Variable Cam Timing
• Compatible with both SR20DE naturally aspirated and SR20DET turbocharged variants
• Withstands high cylinder pressures in boosted applications
• Eliminates gasket failure issues common with composite head gaskets

Cometic's MLS technology uses multiple layers of stainless steel with advanced coating systems to create a gasket that maintains seal integrity under extreme thermal cycling and cylinder pressure variations. The sprocket-stopper layer design controls gasket movement and prevents fretting, while the embossed sealing beads provide targeted clamping pressure around critical sealing areas including combustion chambers, coolant passages, and oil return ports.

This gasket is ideal for performance builds, engine rebuilds, and turbocharged applications where reliability under boost is essential. Proper surface preparation with RA values between 50-60 micro-inches is recommended for optimal sealing performance.
