Genuine Bosch Broadband Knock Sensor

  • Sale
  • $32

Broadband knock sensors provide full spectrum ability for knock sensing on a wide variety of engines.  Can be used with any engine management system with knock sensing capabilities.  Ships with connector plug and pin set.

Optional 10mm spacer kit includes 1/2" spacer to move connector off the mounting surface.  Some engines put the sensor in a position that make seating the connector difficult and puts strain on the wires.  The Mazda rotary engine in particular can benefit from the spacer kit.  Kit includes 10mm x 1.25 bolt to secure the sensor.  This is the correct thread for the Mazda rotary engine.
