Broadband knock sensor. Can be used with Syvecs, AEM, Haltech Pro and Elite, or other engine management systems. 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.
