Knock Sensor does the Job by lasercrow, October 25, 2011

Works like the standard knock sensor and was easy to install on 2002 Impreza Outback Sport. The connector was not the same as the original so when the lead was plugged in it was not a secure connection so I added electrical tape to hold the wire in place. Arrived quickly and the price was fair.

A job that took about 20 minutes. The replacement knock sensor went right in and the connector matched up perfectly. A knock sensor is just a piezo sensor, why pay another 50 bucks for the same unit?
