Bosch 13-62-7-636-937 Ignition Knock Detonation Sensor

The Bosch 13-62-7-636-937 is a precision-engineered ignition knock sensor designed to detect and prevent engine detonation in BMW and MINI Cooper vehicles. This OEM-quality sensor monitors high-frequency engine vibrations characteristic of pre-detonation, transmitting real-time signals to the engine control unit to optimize performance and protect critical engine components.

Key Features:

• Piezoelectric measuring element for accurate knock detection
• Mounts directly to the engine crankcase for optimal vibration monitoring
• High-temperature resistant design for reliable performance under extreme conditions
• Precise signal output enables ECU to adjust ignition timing and fuel mixture
• OEM manufacturer quality ensuring proper fit and function
• Cross-reference: Bosch 0261231224

When the sensor detects engine knock or ping, it relays critical information to the engine computer, allowing the system to adjust timing and fuel delivery to prevent prolonged pre-detonation that can damage cylinder walls, pistons, gaskets, and valves. This genuine Bosch sensor delivers the accuracy and sensitivity required for efficient engine performance and long-term reliability.
