Knock Sensor

The K-Tuned Knock Sensor with Plug (KTD-KNK-400) is an improved replacement option for aged and brittle original knock sensors found in many K-Series engines. Over time, normal engine heat cycles can weaken the plastic body of the OEM sensor, often leading to it breaking when unplugged during engine work. Buyers should check the color of their existing broken sensor to ensure they order the correct replacement. K-Tuned offers this sensor as a direct replacement, aiming to restore proper functionality to your engine's knock detection system. This knock sensor is specifically designed for all 2002 - 2011 K-Series engines that originally came equipped with a green K-Series Knock Sensor. It is important to note that this part does NOT fit newer model 2012+ K24Z series engines.
