Bosch 04271 Distributor Rotor

The Bosch 04271 Distributor Rotor is a precision-engineered ignition system component designed for Mercedes-Benz M119 V8 engines. This critical component rotates on the distributor to direct high-voltage electrical current from the ignition coil through the distributor cap and spark plug wires to create the spark needed for engine combustion.

Key Features:

• Engineered to meet or exceed OEM specifications for reliable performance
• Manufactured from high-quality materials for durability and long service life
• Ensures consistent spark delivery for smooth engine operation
• Direct replacement for OEM part numbers 1191580131, 1191580231, 1191580331, and 1234332422
• Two rotors required per vehicle for V8 applications

Important Installation Note:

This distributor rotor requires the newer style bracket 1191580640 (Bosch 1230328037). If replacing early rotor part number 1191580131, you must use one 1191580640 rotor bracket per rotor to prevent rotor damage or potential fire hazard. Do not use with old style bracket 1191580440.

Maintenance Recommendation:

Replace as part of routine ignition system maintenance along with the distributor cap, ignition coil, spark plug wires, and spark plugs every two years or 30,000 miles for optimal engine performance and fuel efficiency.
