Standard Ignition Distributor Rotor P/N:GB-359
Keep high-voltage spark reaching each cylinder in firing order with the Standard Ignition Distributor Rotor, part number GB-350. It is a direct-fit replacement for the 1986-1993 Mercedes-Benz 300E, 1987-1993 Mercedes-Benz 190E, 1987-1989 Mercedes-Benz 260E, 1988-1989 Mercedes-Benz 300CE, 1988-1991 Mercedes-Benz 300SE, 1988-1991 Mercedes-Benz 300SEL and 1988-1993 Mercedes-Benz 300TE. See the Buyer's Guide tab for engine details.
The rotor turns with the distributor shaft. It carries current from the center terminal of the distributor cap to each outer terminal, which sends it on to the spark plugs.
Signs that a rotor may need replacing include misfires, rough running, hard starting, a burned or eroded tip, and carbon tracks on the rotor. If the rotor is the cause, GB-350 replaces it. The rotor and the distributor cap work together, so inspect the cap at the same time.

This part cross-references / interchanges with the following part numbers:
What does a distributor rotor do?
It turns with the distributor shaft and carries high-voltage current from the cap's center terminal to each outer terminal. From there the current goes to the spark plugs in firing order.
Which vehicles does the GB-350 fit?
It fits the 1986-1993 Mercedes-Benz 300E, 1987-1993 Mercedes-Benz 190E, 1987-1989 Mercedes-Benz 260E and 1988-1989 Mercedes-Benz 300CE, plus other listed models. See the Buyer's Guide tab for the full list.
What are the rotor's segments made of?
Standard Ignition states that its distributor rotors have solid brass segments. They are designed for better conductivity and a higher-voltage spark to the plugs.
Why does carbon tracking matter?
Carbon tracks can give spark an unintended path. This rotor's high-grade dielectric strength alkyd resists dirt sticking, which helps decrease carbon tracking.
How do I know my rotor may need replacing?
Possible signs include misfires, rough running, hard starting, a burned or eroded tip, or visible carbon tracks. Diagnose the cause first, because other ignition parts can produce similar symptoms.
