The intake valve seat with a diameter of 36.6 mm for the BMW Isetta engine (Part No. 1-05991) is suitable for reconditioned cylinder heads with an enlarged seat recess. It enables the professional renewal of the intake valve seat surface and restores compression, sealing, and heat dissipation during engine restoration. This reliably eliminates typical signs of wear in the valve seat area and significantly improves the operational reliability of the Isetta engine.
