TF-Works K-Series Bosch Flat-Response Knock Sensor Conversion Kit

Description

TF-Works K-Series Bosch Flat-Response Knock Sensor Conversion Kit

Upgrade your Honda K-Series engine with modern knock-detection technology. The TF-Works Bosch Flat-Response Knock Sensor Conversion Kit replaces the aging OEM K20/K24 resonant-type sensor with a Bosch flat-response sensor, providing more accurate and tunable knock feedback for standalone ECUs.

Why Upgrade?

The factory K-series knock sensor is a resonant type, tuned to a narrow frequency band that matches the stock bore size. While this works for OEM calibrations, it limits knock detection accuracy once you change away from OEM components. The Bosch flat-response sensor offers a wide frequency range and linear output, allowing your ECU to precisely identify detonation events across varying engine builds — whether naturally aspirated or turbocharged.

Key Benefits

• Improved knock sensitivity across the entire frequency spectrum
  

• Compatible with modern ECUs (Link, Haltech, MaxxECU, MoTeC, etc.) that support wideband knock input
  

• More stable and consistent readings
  

• Plug-and-play mounting hardware included — no guesswork or fabrication required
  

Kit Includes

• Genuine Bosch flat-response knock sensor
  

• Knock sensor stud adapter
  

• Flange nut for secure installation
  

• Fits all K20 / K24 engines using standard block mounting location
  

Installation Notes

• Direct bolt-on replacement for OEM Honda knock sensor
  

• Requires ECU calibration for the new sensor’s flat frequency response
  

• Recommended when converting to aftermarket engine management or building high-output K-series applications
