Description

BOSCH NOS distributor rotor – original German BOSCH quality – Mercedes R107 W126 C126 KA-Jetronic

This BOSCH NOS (New Old Stock) distributor rotor is an original, unused BOSCH part from old factory stock. The rotor was produced during the original production period according to the original BOSCH specifications and quality standards.

The choice of materials, dimensions, and electrical properties are identical to the parts that were fitted at the factory at the time. As a result, this distributor rotor offers more reliable spark transmission, stable ignition timing, and a longer service life than many modern parts.

For Mercedes models with KA-Jetronic This original BOSCH NOS distributor rotor still belongs to the best quality available. Based on our own experience, this NOS version performs better than current production and is therefore particularly suitable for maintenance, overhaul, and original restorations.

Assembly and maintenance tips

When replacing the distributor rotor, always check the condition of the distributor cap, spark plug wires, and spark plugs as well. Worn ignition components can lead to irregular engine operation, power loss, and increased load on the ignition system.

For optimal results, it is recommended to replace the distributor rotor simultaneously with an original BOSCH NOS or high-quality OEM distributor cap.

Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.
