Bosch 996-606-125-01 Ignition Knock Sensor

The Bosch 996-606-125-01 is a precision-engineered ignition knock sensor designed to detect engine detonation and protect your engine from damage. This sensor cross-references to Bosch part number 0-261-231-148 and serves as a direct OE replacement component.

How It Works:

The knock sensor is mounted directly on the crankcase and measures the structure-borne noise using a piezoelectric measuring element. Knock sensors are designed to convert vibration into electric signals to enable the electronic control unit (ECU) to detect knocking combustion and retard the ignition point to prevent damage to the engine. When knocking is detected, the ECU adjusts ignition timing to prevent potential engine damage.

Key Features:

• Genuine Bosch OE quality construction for reliable performance
• Adheres to OEM specs for a guaranteed fit and function
• Operates safely and reliably even at very high temperatures and is extremely robust against changes in temperature
• Piezoelectric sensor element for accurate knock detection
• Precision, reliability, and a long service life are the key features of all Bosch sensors

Performance Benefits:

• Optimizes engine performance and prevents component damage
• Enables maximum energy yield through precise ignition timing control
• Supports use of various fuel grades with different octane ratings
• Helps reduce fuel consumption and increase engine torque

This sensor also cross-references to part numbers 3165141817089 and 3165142960371, ensuring broad compatibility as an OE replacement component.
