Mercedes OM605 OM606 prechamber copper sealing ring set

If you want to increase the performance of your Mercedes OM604, OM605 or OM606 engine enormously, the installation of these prechamber copper sealing rings is an ideal measure to ensure the tight fit of your prechambers, to improve heat transfer and to readjust the distance between the prechamber tip and the piston after an engine overhaul.

Originally, the prechamber is screwed directly onto a shoulder on the cylinder head. This contact point can become leaky over the years and when the prechambers are removed and reinstalled. In addition, after an engine overhaul and the associated decking of the engine block and cylinder head, the distance between the prechamber tip and the piston should be adjusted back to a value above a specific minimum.

Suitable for e.g. OM604, OM605, OM606 and possibly others such as: OM601, OM602, OM603 (please measure!)
