We offer for sale a release spacer for a head made of acid-proof steel, 0.8mm thick. The spacer serves to lower the compression ratio of the engine in order to allow for increased power through the installation of a turbocharger or compressor. The spacer is mounted between the 2 factory head gaskets. The spacer along with the gaskets reduces the compression ratio to about 8.5: 1 depending on the engine and pre-planned head and block surfaces.

The spacer fits the following engines:

– M50 2.5 without Vanos

– M50 2.5 with Vanos

– M52 2.0, 2.5 and 2.8 with a single Vanos

 The product is made in POLAND, burned on a fiber laser.
