Bosch 04177 Distributor Rotor for Mercedes-Benz Engines - V8

The Bosch 04177 Distributor Rotor is a precision-engineered ignition system component designed as original equipment for Mercedes-Benz V8 engines. This rotor serves as the critical conductor that directs high-voltage electrical current from the ignition coil through the distributor cap to each spark plug at precisely the right moment for optimal engine timing and performance.

Key Features:

• Manufactured to stringent OE specifications for exact fit and function
• High-quality materials ensure excellent electrical conductivity and heat resistance
• Direct replacement for Mercedes-Benz OEM part number 000 158 40 31
• Engineered for superior tracking resistance to prevent voltage leakage
• Meets or exceeds original equipment standards for reliability and durability

Common symptoms indicating distributor rotor replacement is needed include engine misfires, rough idling, difficulty starting, reduced fuel efficiency, and diminished engine performance. The rotor should be inspected during routine ignition system maintenance and replaced in tandem with the distributor cap for optimal results. Bosch has been a pioneer in automotive ignition systems since supplying the world's first high-voltage ignition system in 1902, and continues to deliver premium-quality components trusted by technicians worldwide.
