Bosch 0261231142 OE Quality Knock Sensor

The Bosch 0261231142 knock sensor delivers OE quality engine protection with advanced piezoelectric technology that detects engine knock across a wide frequency range. This precision sensor enables your engine management system to optimize ignition timing for maximum performance and efficiency.

Key Features:

• Linear characteristics across large frequency range for accurate knock detection
• Wide operational temperature range for reliable performance in all conditions
• Improves combustion efficiency to reduce fuel consumption up to 9%
• Increases engine torque up to 5% through optimized timing
• Eliminates audible engine knocking for smooth, quiet operation
• OE quality construction meets or exceeds original equipment specifications

Bosch knock sensors use proven piezoelectric technology to monitor engine vibrations and detect detonation in real-time. When knock is detected, the sensor signals the ECU to retard ignition timing, preventing engine damage while maintaining optimal power output. This precise feedback loop allows modern engines to run at their performance edge without risk of harmful pre-ignition.

As a leader in automotive electronics and engine management systems, Bosch brings decades of OE experience to every component. This knock sensor is manufactured to the same exacting standards as the original equipment, ensuring proper fit, function, and long-term reliability.
