Knock Sensor - Genuine Bosch

Overview

Professional-grade genuine Bosch knock sensor that delivers the precise engine protection your turbocharged or high-compression build demands. Essential for safe tuning on any serious performance application, this sensor provides the real-time knock detection data your Haltech ECU needs to protect your engine investment from potentially catastrophic detonation.

Why You Need This

Knock detection isn't optional on modern performance builds — it's engine insurance. Whether you're running a turbocharged 2JZ pushing serious boost, a high-compression LS build, or converting a classic to standalone management, this genuine Bosch sensor provides the critical feedback your Haltech ECU needs to pull timing before knock destroys pistons and bearings. We see too many rebuilt engines that could have been saved with proper knock detection.

The genuine Bosch construction delivers consistent, reliable knock detection across the frequency spectrum where engine knock actually occurs. Cheap aftermarket sensors often fail to detect knock accurately or generate false signals that lead to overly conservative timing maps. This sensor's resonant frequency design specifically targets the 6-8kHz range where knock signatures are strongest, giving your ECU the clean signal it needs for precise ignition control. Critical for turbo applications where knock threshold changes dramatically with boost levels, and equally important for naturally aspirated builds running aggressive timing on pump fuel.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems.
