Bosch 12-14-1-734-580 Knock Sensor for BMW Engines

The Bosch 12-14-1-734-580 is an OE-quality knock sensor designed to detect engine knock and detonation in BMW vehicles. This precision sensor monitors high-frequency vibrations in the engine block caused by abnormal combustion, transmitting critical data to the engine control unit (ECU) to prevent engine damage and optimize performance.

Key Features:

• OEM part number 12141734580 for direct BMW fitment
• Bosch supplier number 0 261 231 072 for cross-reference
• Detects structural vibrations characteristic of engine knock
• Enables real-time timing adjustment for optimal combustion
• Precision piezoelectric sensor technology
• Durable construction for reliable operation in extreme engine conditions
• Direct replacement for worn or failed factory sensors

When the knock sensor detects abnormal combustion vibrations, it sends a signal to the ECU which retards ignition timing to prevent engine damage. This Bosch sensor ensures your engine management system can properly protect against detonation while maintaining peak performance and fuel efficiency. Designed and manufactured to original equipment specifications for reliable, long-lasting operation.
