Supertech BMW M52/M54B25 87.60mm Dia 1.50mm Thick High Boost Cooper Ring Head Gasket

This is a Supertech high boost copper ring head gasket designed for BMW M52 and M54B25 engines. It features an 87.60mm bore and a 1.50mm thickness, making it suitable for builds that require a stronger seal under higher cylinder pressures.

The copper ring construction is key here. Unlike standard multi-layer steel gaskets, the copper ring provides a more robust seal, especially in high-boost applications where cylinder pressures can significantly increase. This design helps prevent leaks and maintain compression, which is crucial for performance and reliability when you're pushing the engine harder. The 1.50mm thickness is a common choice for many performance builds, offering a good balance between sealing and maintaining proper compression ratios.

When installing this gasket, ensure your engine block and cylinder head surfaces are perfectly clean and flat. Proper preparation is essential for the copper ring to seat correctly and provide the intended seal. This gasket is a solid option for BMW owners looking to enhance their engine's sealing capabilities for performance tuning.
