Cometic C4600-140 MLS Cylinder Head Gasket 87mm Bore .140 inch Nissan SR16VE/SR20VE

The Cometic C4600-140 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan SR16VE and SR20VE engines. This premium gasket features a .140 inch compressed thickness and 87mm bore diameter, making it ideal for high-compression builds and performance applications where precise quench control is needed.

Advanced MLS Construction:

• 5-layer stainless steel construction for superior strength and durability
• Embossed outer layers coated with Viton fluoroelastomer for extreme temperature resistance
• Load-controlled embossments distribute clamping pressure evenly across sealing surfaces
• Uncoated stainless steel center layer adjustable for precise thickness requirements
• Resists corrosion and withstands extreme cylinder pressures

Performance Benefits:

• Requires less clamp load than conventional gaskets, reducing bore distortion
• Excellent rebound characteristics maintain seal integrity under thermal cycling
• No sealants or re-torque required when properly installed
• Ideal for aluminum head to cast iron block applications
• Proven durability in high-output street and racing applications

Important Installation Note: MLS gaskets require smooth, flat mating surfaces with a finish of 50 RA (roughness average) or finer for optimal sealing performance. This gasket is designed without extra oil holes—verify oil passage alignment before installation.
