Metal gaskets are known for their very long service life. You save the cost of buying two head gaskets and a compression-reduction plate. The spacer plate is reusable.

When converting to a turbocharger or supercharger, the compression ratio must be reduced. This can be achieved with special pistons or a spacer plate. This allows significantly higher boost pressures and power outputs. Under forced induction, the original pistons would not withstand the resulting temperatures at standard compression ratios.

Overview of available thicknesses and compression ratios:

• Standard compression ratio – 1.6mm
• Compression ratio 8.92:1 – 2.1mm
• Compression ratio 8.57:1 – 2.6mm
• Compression ratio 8.25:1 – 3.1mm
• Compression ratio 7.96:1 – 3.6mm
• Compression ratio 7.69:1 – 4.1mm
• Compression ratio 7.44:1 – 4.6mm
• Compression ratio 7:1 – 5.6mm (on request)
