Standard Ignition GB-359 Distributor Rotor

Distributor Rotor for Mercedes-Benz V8 Ignition Systems

Standard Ignition GB-359 is a bolt-on distributor rotor built for Mercedes-Benz ignition service on select 1990-1995 V8 applications. It uses a phenolic rotor body with a brass contact material and a black finish for a direct replacement style repair.

Key Features

• Bolt-on mount type for straightforward distributor rotor replacement
• Brass contact material for consistent spark transfer
• Phenolic rotor material for ignition system durability
• Black color/finish
• Includes distributor rotor only
• Standard Ignition GB-359 part number for catalog matching

Detailed Product Information

This Standard Ignition distributor rotor is a direct-fit ignition component for Mercedes-Benz E420, S420, S500, SL500, E500, 400E, 400SEL, 500E, 500SEC, 500SEL, 500SL, and 400SE applications listed below. The brass contact helps carry ignition energy through the distributor, while the phenolic rotor body provides the insulating structure needed for proper spark routing. If you are servicing a Mercedes-Benz 400E distributor rotor, a Mercedes-Benz S500 ignition rotor, or a Mercedes-Benz SL500 distributor rotor, GB-359 is the catalog reference to verify.

This part cross-references D700 and RB963 for the same application.

What It Helps Address

• Misfiring caused by worn rotor contacts
• Hard starting related to distributor ignition wear
• Intermittent spark delivery inside the distributor
• Ignition performance loss from heat- or age-related rotor damage
• Service replacement for cracked or deteriorated rotor material

Installation Notes and Tips

Confirm distributor cap and rotor indexing before installation and compare the old part to the new GB-359 rotor for mounting style and terminal layout. Clean the distributor interior before assembly, and inspect the cap, wires, and related ignition components at the same time to avoid repeat service. Verify vehicle application by year, make, and model before ordering.
