Bosch 1234332337 Ignition Distributor Rotor OE Replacement

The Bosch 1234332337 is an OE-quality ignition distributor rotor engineered for early-style distributors found in Mercedes-Benz M116 and M117 V8 engines. Manufactured in Germany, this rotor carries OEM part number 04143 and is built to Bosch's original equipment specifications — the same standards Bosch has maintained since supplying the world's first high-voltage ignition system in 1902.

A worn or degraded rotor can cause misfires, rough idling, and poor fuel economy. Bosch distributor rotors feature high tracking resistance and are constructed from premium materials to ensure reliable spark distribution and long service life.
