Cometic MLS Head Gasket for VAG 1.8L & 2.0L Engines

The Cometic WC4247-098 Head Gasket is a high-performance cylinder head gasket developed for selected Volkswagen and Audi 1.8L and 2.0L engines.

Designed for demanding engine builds, this gasket combines an 83.00mm bore diameter with a 2.49mm (.098″) compressed thickness, making it particularly suitable where a thicker-than-standard head gasket is required as part of a professionally calculated engine specification.

Cometic is widely recognised in performance and motorsport applications for its advanced metal gasket technology. The MLS – Multi-Layer Steel – construction uses multiple layers of stainless steel to provide a strong and stable seal between the cylinder head and engine block.

This construction is particularly valuable in engines operating under increased cylinder pressure, high temperatures or modified performance conditions.

Why Choose a Cometic MLS Head Gasket?

A cylinder head gasket must maintain an effective seal between the combustion chambers, coolant passages and oil galleries while operating under extreme heat and pressure.

The Cometic MLS design is engineered to provide:

• Excellent resistance to high combustion pressure
• Strong sealing performance
• Improved durability compared with many conventional composite gasket designs
• Stainless-steel construction for corrosion resistance
• Excellent dimensional stability under demanding operating conditions
• Suitability for naturally aspirated, turbocharged and motorsport engine builds
• A range of gasket thicknesses for specialist engine configurations

The 2.49mm thickness of WC4247-098 can also be useful when an engine builder requires additional gasket thickness as part of a calculated compression ratio, piston-to-head clearance or modified block/head configuration.

Performance Applications

The Cometic WC4247-098 may be particularly suitable for professionally built engines including:

• Performance road cars
• Turbocharged engine builds
• High-compression or modified engines
• Motorsport engines
• Track cars
• Rally cars
• Race engines
• Engine rebuilds requiring a specific gasket thickness
• Modified cylinder head or block combinations

The correct gasket thickness should always be selected according to the individual engine specification rather than simply replacing the original gasket with a thicker version.

Important Fitment Information

Please confirm engine code, cylinder bore and required gasket thickness before ordering.

This product has an 83.00mm bore and 2.49mm (.098″) thickness and is intended for specific Volkswagen/Audi 1.8L and 2.0L engine applications.

A thicker head gasket can alter:

• Compression ratio
• Piston-to-cylinder-head clearance
• Camshaft timing relationship
• Combustion chamber geometry

For modified engines, final suitability should be confirmed by your engine builder or tuner.

Installation Recommendations

For best results:

• Ensure the cylinder head and block sealing surfaces are correctly prepared
• Check both surfaces for flatness
• Follow the engine manufacturer’s tightening procedure
• Use the correct torque sequence
• Replace torque-to-yield cylinder head bolts where specified
• Consider performance head studs where appropriate for the engine build
• Confirm piston-to-head and valve clearances on modified engines
• Do not select gasket thickness solely to compensate for an incorrectly machined cylinder head or block

Professional installation is recommended for performance and motorsport engines.

FAQs

What is the bore size of Cometic WC4247-098?

The gasket has an 83.00mm cylinder bore.

What thickness is WC4247-098?

WC4247-098 has a compressed thickness of 2.49mm, equivalent to approximately .098 inch.

Is WC4247-098 an MLS gasket?

Yes. It uses Multi-Layer Steel (MLS) construction designed to provide strong sealing performance under demanding engine operating conditions.

Is this suitable for modified engines?

It can be suitable for modified, performance and motorsport engines when its bore diameter and compressed thickness match the required engine specification.

Can a 2.49mm head gasket reduce compression ratio?

Increasing head gasket thickness can increase combustion chamber volume and therefore potentially reduce static compression ratio. However, the effect depends on the complete engine specification and should be calculated by the engine builder.

Does this gasket fit every VW or Audi 1.8L and 2.0L engine?

No. Volkswagen and Audi have produced many different 1.8L and 2.0L engine families. Engine code, bore size and gasket design must be confirmed before purchase.

Should new cylinder-head bolts be installed?

If the engine uses torque-to-yield head bolts, new bolts should normally be installed according to the manufacturer’s service procedure. Performance builds may use suitable aftermarket head studs where specified by the engine builder.
