Bosch 0261231046 OE Quality Knock Sensor

The Bosch 0261231046 is an OE-quality knock sensor engineered to deliver precise detonation detection and optimal engine protection. As a global leader in fuel injection and engine management components, Bosch manufactures this knock sensor to the same exacting standards as original equipment parts found on the assembly line.

The knock sensor continuously monitors engine vibrations and sends real-time signals to the engine control unit (ECU), allowing the ignition timing to be adjusted instantly when pre-ignition or detonation is detected. This closed-loop correction protects internal engine components from damage while keeping the engine operating at peak efficiency.

Key Features:

• OE-quality construction meets or exceeds original manufacturer specifications
• Improves combustion efficiency and can reduce fuel consumption by up to 9%
• Increases torque output by up to 5% through optimized ignition timing
• Enables precise, real-time knock detection to protect engine internals
• Direct OE replacement — no modifications required for installation
• Manufactured by Bosch, the world's largest supplier of OE fuel injection and engine management components
• Durable piezoelectric sensing element for long service life

Bosch knock sensors are trusted by OEM manufacturers worldwide and are an ideal replacement for worn or failed sensors. Restoring proper knock sensor function helps prevent engine damage, restore fuel economy, and maintain performance over the long term.
