- All K-Series Engines
*Excludes K24Z – Series
Many K-Series cars come with a very brittle and easily broken knock sensor. If you have worked on your car and tried to unplug the sensor chances are you’ve broken it. The plastic body becomes very weak from the heat and often cracks or breaks easily. We are providing a better alternative with our knock sensor with pigtail. This can easily be wired into your and doesn’t require any modification to the ECU. The readings and output are the same as factory.
