Review on 🔝 Bosch 65018 Knock Sensor: Unparalleled Performance and Reliability by Grant Galloway

!WARNING! The item I received did not work immediately. The included wiring harness did not fit the sensor and my car. Check for continuity from the bottom of the center hole to the contact inside the connector. In my case the coil had continuity to the right output pin, but the harness was built for the left pin on the coil. In addition, the output of the wiring harness, the connection to the output of the sensor, had to be connected to the right side contact, but was designed for the left side contact. After correctly rebuilding the wiring harness (which came with the coil) it worked perfectly. I have experience repairing wiring harnesses so this was easy for me.
