Beisan Systems Vanos Solenoid Seals. Recommended with all S50B30 (Euro) Vanos overhauls.

These are in fact Genuine BMW parts sourced from the S62 engine, as they feature a double-faceted design for increased durability and pressure holding. Because of their flat interior, these form rings must not be twisted during assembly.

Priced per set – not included in the standard Beisan Systems Vanos Seals Kits.
