The Cometic C4294-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW S14B20 and S14B23 engines. This high-performance gasket features a 93.4mm bore diameter and a .070" (1.78mm) compressed thickness, making it ideal for performance applications and engine builds requiring precise compression control.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 93.4mm bore diameter for proper combustion chamber sealing
• .070" compressed thickness allows for compression ratio tuning
• Designed for BMW S14B20 and S14B23 4-cylinder engines (E30 M3)
• Provides excellent resistance to extreme cylinder pressures and temperatures
• Embossed active sealing technology for optimal sealing at combustion chamber and coolant passages

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, providing the strength and flexibility needed to seal high-performance engines. The layered construction allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping pressure. This gasket is essential for rebuilds, performance upgrades, or when replacing worn factory gaskets on BMW's legendary S14 engine platform.
