Bosch 119-158-02-31 Distributor Rotor for Mercedes-Benz Engines - M119 V8

The Bosch 119-158-02-31 distributor rotor is an essential OEM-quality ignition component designed specifically for Mercedes-Benz M119 V8 engines. This precision-engineered rotor serves as the critical conduit that rotates on the distributor shaft, directing high-voltage electricity from the ignition coil through the distributor cap to the spark plug wires, ensuring proper firing sequence and optimal engine combustion.

Key Features:

• OEM Bosch quality engineered to meet or exceed factory specifications
• Durable construction designed to withstand high temperatures and electrical loads
• Precise contact design ensures reliable spark transfer and consistent timing
• Direct replacement for Mercedes-Benz part numbers 1191580231, 1191580331, and A1191580231
• Also known as Bosch 04271 and cross-references with 1234332422

Important Installation Note: This updated rotor design requires the newer style bracket 1191580640 (Bosch 1230328037) for proper installation. If replacing early rotor part number 119-158-01-31, the updated bracket must be used to prevent rotor failure or potential fire hazard. M119 engines require two rotors per vehicle, one for each distributor.

Maintenance Recommendation: Distributor rotors should be replaced as part of routine ignition system maintenance along with distributor caps, spark plugs, and spark plug wires every two years or 30,000 miles. Worn contacts on the rotor can prevent proper spark transfer, leading to engine misfires, rough idling, difficulty starting, and poor acceleration.

Restore your Mercedes-Benz ignition system to peak performance with this genuine Bosch distributor rotor, backed by over a century of ignition system engineering expertise.
