Product Description

Mustang 4V Knock Sensor
Prevent engine damage on your Cobra or Mach 1 with this replacement engine knock sensor! Knock sensors are a vital part of your engine's monitoring system. They detect cylinder knock and retard timing to prevent engine damage. Being attached to the block in the valley of the engine, they are subjected to high amounts of heat. Over time, this can cause the sensor leads and sensors themselves to become brittle and break. If you have a faulty or broken sensor, replace your sensor with this Ford original replacement!

Fitment Note
Will not fit 03/04 Cobra as the block had no provisions for knock sensors.

-Fits 1999-2001 Mustang Cobra
-Fits 2003-2004 Mustang Mach 1
